Answer 1

1/5 (5) = 5/5, or 1 cup of blue paint

1/3 (5) = 3/5, or 0.6 cup of yellow paint.

Answer 2

`(5)/(3)` cups

Explanation:

Jacob mixes
`(1)/(3)` cup of yellow paint for every
`(1)/(5)` cup of blue paint to make green paint.

The ratio of yellow paint to blue paint =
`(1)/(3):(1)/(5)`

= 5:3

`(1)/(5)` cup of blue paint =
`(1)/(3)` cup of yellow paint

1 cup of blue paint =
`(1)/(3)/(1)/(5)` cup of yellow paint

`\Rightarrow (1)/(3)/(1)/(5)`

`\Rightarrow (5)/(3)`

Hence, For 1 cup of blue paint needed
`(5)/(3)` cups of yellow paint.
