Let X be the number you want to find.

7% * X = 84

7x/100 =84

x= 1200

84 ÷ 7%
= 84 ÷ 7/100
= 84 x 100/7
= 8400/7
= 1200

100/7 x 84 = 1200

Assume that 7 percent of X is 84
This means X (7 / 100) = 84
0.07 X = 84
X = 84 / 0.07
X = 1200
7 percent of 1200 is 84

84 / 7 = 12
so 12 is ONE percent.
if you want 100%, you times 12 by 100.
so 1200

7 % of a number = 84

Let the number = X

7% * X = 84
7/100 *X = 84
X = 84 *100/7
X = 1200

1200

7's into 84 go 12 times. So 12 is 1%. Times that by 100!

1 times 84

84 divided by .07= 1200
