Question

What is a related equation to this equation?

18/a = 7

A. a = 7/18

B. a + 7 =18

C. a = 18/7

D. a = 18 * 7

Answer 1

Simple.....

you have
`(18)/(a) =7`

to find what a is....simplify/multiply both sides....


`a* (18)/(a) =7*a`

simplifying it too....

18=7a


`(18)/(7) = (7a)/(7)`


`(18)/(7) =a`

Thus, your answer, C.
