Making Equivalent Fractions
P-PEF 1
Instructions: An equivalent fraction can be made by multiplying the top and bottom numbers of a fraction by the same number. The problems below show this being done, but the number that is being multiplied by is missing. Write the missing number in the boxes. (Hint: you can use a multiplication table to help you.)
1 4?2 = 8 10 ? 2 20
2 2? = 6
5?

3 3 ? = 24

4 7 ? = 35 10 ? 50

10 ? 25 ?

9? 25 ?
=
54 150
Instructions: The process of making an equivalent fraction works the same for division. For these problems, find the missing number that the top and bottom numbers are being divided by.
1 4?4 = 1 20 ? 4 5
2 25 ? = 5

Equivalent Percent Form
Instructions: Convert each of these factions into an equivalent fraction that has 100 as the bottom number. Then write that fraction in its percent form. (Some will need to be converted by multiplying and others by dividing.)

Equivalent Fractions: Unknown Top Number
Instructions: In each pair of equivalent fractions below, a top number is unkown. Figure our what the relationship between the bottom numbers is. (In other words, figure out what was multiplied or divided by to get the new bottom number) Then do that same thing to the top number to find the unkown value (n).
Example
2 5
? 6
=
? 6
n 30
so to find `n', we also multiply by 6.
n = 2 ? 6 n = 12
to go from 5 to 30, we have to multiply by 6
