3. Mr. Bishop has 28 students in one

class and 32 students in another class. He wants to divide both classes into small groups for their Science experiment next week. Which of the following could be the number of students in each group

28 students

32 students

Divide both small groups

?? Could be # students in each??

3. 28 students

32 students

Divide both small groups

?? Could be # students in each??

Look for a common factor 28: 1 x 28, 2 x 14, 7 x 4 32: 1 x 32, 2 x 16, 4 x 8 Remember a common factor is

shared by both products!

The common factors of 28 and 32 are: 1, 2, and 4

Look at your answer choices 3 – not a common factor 6 – not a factor at all 7 – not a common factor 4 ** Here’s your answer

3: 3, 6, 9, 12, 15, 18, 21, 24 6: 6, 12, 18, 24* 8: 8, 16, 24*

The smallest common multiple is 24

7. Write 3 and 1/8 as an improper

fraction and draw a model (picture) to prove your answer.

3 and 1/8

3 WHOLE parts

1/8 part

The only denominator I see is 8, so your drawings need to be divided into 8 pieces.
