Answer 2

Answer:

A valid proportion that can be used to solve the problem is $\frac{12}{1}=\frac{x}{7.5}$

Step-by-step explanation:

Given : Rosa earns $12 per hour.

we have to find a valid proportion that can be used to solve the problem if she works for 7.5 hours and earns x dollars.

Let $\frac{a}{b}$ denotes the fraction where x represents the amount she earns and b denotes the hours she works.

Thus, proportion becomes,

$\frac{12}{1}=\frac{x}{7.5}$

Solving for x, we get,

Cross multiply, we get,

$x=7.5\times 12$

Solving further , we get,

$x=90$

Thus, a valid proportion that can be used to solve the problem is $\frac{12}{1}=\frac{x}{7.5}$
