The answer is 9.
Since you cross multiply 3 times 45 which is 135. Then divide 135 by 15

Answer:


x = 9

Explanation:

1 ) Cross-multiply...


(3)/(x) ÷
(15)/(45)


3 ×
45 = 15 ×
x


135=15x

2 ) Flip the equation...


15x=135

3 ) Divide both sides by 15...


(15x)/(15) =
(135)/(15)


x = 9

Hope this helps! :)
