Question

to get baby-blue paint, Farid needs to mix 5 parts blue paint with 2 parts white plant. Farid mixes 20 cups of blue with 8 cups of white

Answer 1

4 baby blue paints

Explanation:

Given

Let b represents blue paint and w, white paints

`b : w = 5 : 2` ---for 1 paint

Required

The number of paints in
`20 : 8`

To do this, we set the following equivalent ratios

`5n:2n = 20 : 8`

Where n represents the number of paints

By comparison

`5n = 20`

`2n = 8`

Solve for n in both cases;

`5n = 20`

`n = (20)/(5)`

`n = 4`

`2n = 8`

`n = (8)/(2)`

`n = 4`
