Answer:

The value of r is 4

Step-by-step explanation:

\frac{r}{4}  =  \frac{60}{120}

In order to find the value of r, you need to get rid of denorminator. By multiplying 4 to both sides:

(r/4)×4 = (60/120)×4

r = (1/2)×4

= 2

r = 2

r/4 = 1/2

Multiplying both sides by 4 removes the fractions, yielding r = 2
