1.) 3/1 x 1/8 = 3/8

2.) 1 1/5 x 2/5 = 6/5 x 2/5 = 12/25

Part 1

A) Video of my Quiz
(No Video)
Question 1
Determine 3 x 5/18, in lowest terms.
A. 5/6 B. 5/9 C. 5/18 D. 5/54

My answer was A.

Show your work.

3 x 5 = 15
1 x 18= 18

15/18 in lowest terms is 5/6







B) Multiplying Fractions

I will use question 6 to explain how you can multiply fractions.

1) One way is to use 4 pictures of 1/2

1/2
1/2
1/2
1/2

Then add them together

1/2 + 1/2 + 1/2 + 1/2= 2/2 2/2

Your answer would be
2 or 4/2

2) The Second way to do it is to use a number line

Just draw a horizontal line and label is 0, 1, 2 then keep adding the halves together.



C) Dividing Fractions

I used question 5 from the text book to help me explain how to divide fractions.

One way you can show you divided a fraction is by using a fraction strip. Then you divide the strip into even smaller pieces then take the half the original amount of strips.




Another way you can divide a fraction is by multiplying the denominator of the fraction by the divisor.




4/8 divided by 2 = 4/16
8x2



D) Word Problems


7. A pitcher of orange juice is 2/3 full. If four students equally share the juice, what fraction of the full pitcher does each student get?

To solve word problems, you have to find what it is asking. For example, in this question it is asking you to divide the pitcher of orange juice between 4 students. Then you set up a simple sentence answer. Next, you solve the problem. Lastly, you fill in the sentence.

Each student will get 2/12 or 1/6 of the pitcher.

I need to find what 2/3 divided by 4 will equal.

2/3 divided by 4 = ?

PART 2
Fraction x Fraction














How I solved it:
Multiply 1 by 2 and you will get 2 (numerator)
Multiply 5 by 7 and it's 35 (denominator)
the answer is 2/35 (try to convert it as small as possible)





Mixed Number x Fraction














How I got the answer:
Step 1: Multiply the whole number by 6 and it equals 6..... Then add the 5 to the 6 and you will get 11...
so its 11/6

Step 2:
Multiply 11/6 with 3/10 and you will get 33/60.

Step 3: Simplify it....
divide it by 3
The answer would be 11/20





Mixed Number x Mixed Number











How I got it:


Step 1: Multiply 5 by 12 and then add 2 so you will get 62/12
Step 2: Multiply 4 by 23 and add 6 and you will get 92/23
Step 3: multiply 62/12 by 92/23 and you will get 5704/276
Step 4: Then divide it.... 276 will go to 5704 20 times and there will be 184 remaining. So its (20) 184/276
Step 5: Simplify
I simplified it by 4 and i got (20) 46/69

So the answer is (20) 46/69

Jenn's Fraction Growing Post !

Over the Past Few weeks we have been learning about dividing and multiplying fractions ! Here is my growing post .

a)I recorded a video, but I couldn't find it ;(

b) Using one question from questions 6 or 7 on page 202 of the textbook, explain two ways to multiply a fraction by a whole number. You should use pictures to help explain. -

the question i chose was 4 x 1/2 !
one way you could do this equation is to draw 4 groups of 1/2 to get the answer of 4/2 or 2.

another way you could do the equation is 4/1 x 1/2 . You multiply the 2 numerators first and then you multiply the two denominators .

c) Using one question from questions 4 or 5 on page 208 of the textbook, explain how to divide a fraction by a whole number. You should use pictures.

To divide a fraction, you cut it into how many rows the whole number is. Since the fraction is one half, you can shade in one half of the whole. After that, since the fraction is still one half, it means you can have one fourth of the shaded section. That concludes to the answer being one eighth.



d)A pitcher of orange juice is 2/3 full. If four students equally share the juice, what fraction of the full pitcher does each student get?

The Answer ? Each student gets 2/12 or 1/6 of the full pitcher of orange juice.
2/3 divided by 4 = 2/12 or 1/6 (simplify )

Part two .

Fraction x Fraction

To do Fraction x Fraction you simply multiply the denominator and numerator to get the answer.


Mixed number x A Fraction

first off you , make the mixed fraction into a fraction to do that you have to multiply the whole number by the denominator then add the numerator. After you have done that , you have to do the fraction, then you just multiply both the denominator and numerator to get the answer.


Mixed Number x Mixed Number

To multiply a mixed number by a mixed number is suprisignly very simple. All you must do is convert both of the mixed numbers into fractions then you multiply both fractions to get the answer. After that, you must simplify your answer then divide it to get your final answer. (:

One way to solve 4x1/2 is with pictures.

Another way to solve 4x1/2 is to multiply both denominators and numerators.

PART 2

How to Multiply a Fraction by a Fraction
The first step to multiply a fraction by a fraction is to multiply the first fraction's numerator with the second fraction's numerator. Next, you have to multiply the first fraction's denominator with the second fraction's denominator. Finally, to get your answer, you take the answers from the numerator multiplied by the other numerator question and the denominator multiplied by the other denominator and make a fraction of the answers (Simplify if possible).

How to Multiply a Fraction by a Mixed Fraction
The first thing I did to multiply a fraction by a mixed number is to convert the mixed number to an improper fraction by multiplying the whole number by the denominator. Then you take that answer and add te numerator. Next you make that answer a fraction by just taking the denominator and adding the last answer on top of it. After that you multiply the numerator with the improper numerator and multiply the denominator with the improper fraction's denominator. Finally, you convert the improper fraction into a mixed fraction by counting how many times the denominator fits into numerator and make the remainder into a fraction(Simplify the fraction if possible).

How to Multiply a Mixed Fraction by a Mixed Fraction
The first step you're supposed to do when you are multiplying a mixed fraction with a mixed fraction is to make both of the mixed fractions into improper fractions. Then you multiply the numerators and the denominators. Next, you get the answer's numerator and denominator and you find out how many times the denominator fits into the numerator. After that, you make the remainder into a fraction (Simplify if possible). That is how you multiply two mixed fractions.
