Question

Find the missing number of each unit rate

Answer 1

3 and 4

Explanation:

21/7 = x/1

x = 21/7*1 = 3

16/4 = y/1

y = 16/4*1 = 4

Answer 2

all you need to do is cross multiply for each one and then solve

`21 = 7x`
and

`16 = 4x`
then you solve which gives you 3 and 4 for your missing values
