Question

Solve the proportion: Round answer to nearest tenth, if necessary: r =_____

Answer 1

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

Answer 2

Answer:

r = 2

Step-by-step explanation:

Note that 60/120 reduces easily to 1/2.  Then we have:

r/4 = 1/2

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