Question

What number is 45% of 60, as well as 8 is 0.5% of what number?

Answer 1

Hi!

We can set up proportions to solve these.

1.
`(x)/(60) (45)/(100)`

2.
`(8)/(x) (0.5)/(100)`

Cross multiply to solve for x

1. 60 x 45 = 2700
2700/100 = 27

2. 8 x 100 = 800
800/0.5 = 1600
(Tip: dividing by 0.5 is the same as multiplying by 2)

The answers are
1. 27
And
2. 1600

Hope this helps! :)
