Question

X-30% is 12. What is X?

Answer 1

If i'm not wrong,i think the answer is:

30％=0.3
X=0.3+12=12.3

Answer 2

Since we're trying to find X, what is X? X is the whole. I'm using the "Part = Percent x Whole" formula (Whole = Part ÷ Percent) to find the answer. 12 ÷ 0.3 (30% in decimal form) = 40. And we can do the opposite to see if it's right, 40 x 0.3 = 12.

Hope this helps,
