n X .15 = 9 9 / .15 = n 9 / .15 = 60

If you know that n = 15, substitute 15 for n and solve: n + 3 - 9 15 + 3 - 9 9

15 + n = 24 (subtract 15 from both sides) n = 9

It is an equation and the value of n is 6

n=6

It is an equation and the value of n is 6

9/12 = 15/20

9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1

n=6

9 out of 15 equals 60%

n = 8

3n = 15 + 12 = 27, 27/3 = 9 = n
