Write three equivalent ratios
To solve these questions, we do the following:
Whatever is being applied to a part of the ratio must be done on the other part
Solving (9):

Multiply through by 2

Multiply through by 3

Multiply through by 5

Hence, the equivalents are:

Solving (10):
Ratio = 1.5 to 3.5
Multiply by 2


Multiply by 3


Multiply by 4


Hence, the equivalents are: 3 to 7, 4.5 to 10.5 and 6 to 14
Solving (11):
Ratio = 6.25 to 1.25
Divide by 5


Multiply by 2


Multiply by 4


Hence, the equivalents are: 1.25 to 0.25, 12.5 to 2.5 and 25 to 5
Solving (12):

Multiply by 2


Multiply by 4


Multiply by 6


Hence, the equivalents are: 6:7, 12:14 and 18:21
Solving (13)

Convert mixed fraction to improper fraction

Multiply by 2


Multiply by 3


Multiply by 12


Hence, the equivalents are: 10/3:5/2, 5 : 15/4, and 20:15
