Gilberts Fractions Growing Post

In the past couple of classes we've been learning how to multiply and divide fraction so here's a post for how to do it.

Multiplication
OK so there are two ways to find the answer one way is to use a diagram. As you see in my picture I have showned you how to do that. The second is the easier way all you have to do is multiply the both denominators and numerators to get the answer.

DivisionOK so to divide a fraction you have to draw a diagram. After you have done that you you split it into 1/2 then shade in 1 after that you split it into four horizontally and shade in 1. Then you get 1/8.


Word Problem

Iqaluit has frost on about 3/4 of the days in a year. It has frost on five times as many days as Vancouver. On what fraction of the days of the year does Vancouver have frost?

To get theis answer all you have to do is the follow the steps I wrote on division.

Part 2

Fraction x Fraction

To do Fraction x Fraction all you have to do is multiply both the denominator and numerator to get the answer.


Mixed number x A Fraction

OK so all you have to do is 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 fractions then you just multiply both the denominator and numerator to get the answer.


Mixed Number x Mixed Number

OK to multiply a mixed number by a mixed number is very simple. All you have to do is convert both mixed numbers into fractions then you multiply both fraction to get the answer. After that you simplify your answer then divide it to get your final answer.
