Answer 1

`Fraction = (5)/(7)`

Step-by-step explanation:

Given

`black: red = 2 : 5`

Required

Determine the fraction of red

First, we calculate the total ratio.

`Total = black + red`

Substitute values for black and red

`Total = 2 + 5`

`Total = 7`

The fraction of red is then calculated as:

`Fraction = (Red)/(Total)`

`Fraction = (5)/(7)`
