chapter 7 multiply fractions

this is for your notes and review

Lesson 1

• in this lesson, you will find this very easy and it is

• Here is an example of the lesson

• Maya collects stamps She has 20 stamps in her collection 4/5 of the stamp has been canceled how many of the stamps in Maya has collection have been cancelled

• Since you want to find 4/5 of the stamps you should arrange them into equal groups or any easy way is to do it standard version

• 4/5 of 20 is ______, or 4/5 × 20 = ______

• 4/5 ×20 = 16

• 20 ÷ 5 = 4 then 4×4 = 16 !6 is your answer

Lesson 2

• example what we learned in the last lesson was pretty simple well we're just going to take one step forward for this one

• for this lesson, we will be doing practically the same thing and we're going to be using 1/9 × 3

• step 1 you take the 3 and make it into a fraction by putting a 1 under the 3 and make it 3/1

• step 2 what is 9 × 1 = 9

• step 3 3 x 1 = 3

• answer 3/9

• so that is the lesoon

Lesson 3

• lesson 3 is the same exact lesson as lesson 2

• here let me give you some examples what if we do 3 x 2/5

• what is the first thing we're supposed to do? the first thing we're supposed to do is make 3 into a fraction that would be 3/1

• the next time we're going to do is multiply the denominators what is 1 x 5 that is 5

• that would be our denominator the next thing we're going to do it is multiply the numerators what is 3 x 2 that is 6

• now when you put this fraction together you got an improper one 6/5 now you have to make it into a mixed number

• and you all know how to do that cause you should have learned in 3rd grade

If you want more of the lesson I will post more of lessons thank you
