Answer 2

A) 250y = 800

Explanation:

Given equation:

`(8)/(250)=(y)/(100)`

Cross multiply by multiplying the numerator and denominator of the first fraction by the denominator of the second fraction, and multiplying the numerator and denominator of the second fraction by the denominator of the first fraction:

`\implies (8 * 100)/(250* 100)=(y * 250)/(100 * 250)`

Simplify:

`\implies 8 * 100 = y * 250`

`\implies 800=250y`

`\implies 250y=800`
