### Darlene's Fraction Growing Post

Part 1

A) Video

B) Textbook Pg 202, Question 6

Fraction: 3x3/8
C) Textbook Pg 208, Question 4

Fraction: 1/4/2
D) Textbook Pg 208, Question 7

A pitcher of orange juice is 2/3 full. If 4 students equally share the juice, what fraction of the full pitcher does each student get?
Part 2

E) Fraction x Fraction

Fraction: 2/3 x 5/6
F) Fraction x Mixed Number

Fraction: 1 1/5 x 2/5

Turn the mixed fraction into an improper fraction by multiplying the whole number and the denominator, then add the numerator. Use that as a new numerator and use the same denominator from the mixed number. Then you multiply the numerators and denominators to get the answer.
G) Mixed Number x Mixed Number

Fraction: 2 3/4 x 2 3/4

Turn both mixed numbers into an improper fraction by multiplying the whole number and the denominator, then add the numerator. Use that as a new numerator and use the same denominator from the mixed number. Then you multiply the numerators and denominators, and convert the improper answer back to a mixed number.

The pictures are dark because the lights were off in my room and I was too lazy to turn the lights on. Sorry ^_^

Part 3

Division

Fraction: 1 1/2 / 3/4

Turn the mixed fraction into an improper fraction by multiplying the denominator and the whole number together and then add the numerator. Use the answer as a new numerator and use the old denominator. Replace the mixed fraction with the improper fraction and start the division. For the first way, you can cross multiply by multiplying the numerator of one fraction together with the other denominator from the other fraction and you do the same with the other denominator and numerator. Then you can just simplify the answer into lowest terms.
Fraction: 3/4 / 1/2
