Question

What is the solution to the equation 9r=4/7

Answer 1

`r=(4)/(63)`

Explanation:

1) Divide both sides by the same factor

`9r=(4)/(7)`

`(9r)/(9) =((4)/(7) )/(9)`

2) Simplify

• Cancel terms that are in both the numerator and denominator

`(9r)/(9) =((4)/(7) )/(9)`

`r=((4)/(7) )/(9)`

• Divide the numbers

`r=((4)/(7) )/(9)`

`r=(4)/(63)`

Answer 2

r=4/63

Explanation:

Divide each term in 9r=47 by 9 and simplify.
