To find the original amount, you divide the product by the percentage.
112.79 / 0.15 ≈ 751.933 (the 3's repeat infinitely).
To check your answer, multiply 751.933 by 0.15.
751.933 * 0.15 = 112.78995 ≈ 112.79
Answer:
a=2, b=5
Step-by-step explanation:
Let
n -----> the denominator
we have

Solve for n
That means -----> isolate the variable n
Multiply by n both sides

Divide by 3.5*10^4 both sides

therefore
a=2, b=5
Let the unknown number be y;
3×3×3×11×11×y = 16335;
3267×y = 16335;
y = 16335/3267;
y = 5;
