Answer: 34.2857142857
Step-by-step explanation: To answer the question 35% of what number is 12, we translate the question into an equation.
First we have 35% which we need to write as a decimal and we can do this by moving the decimal point two places to the left and if we fill in the missing position with a 0, we get 0.35.
Next, "of what number" means 0.35 multiplied by X or (0.35) (X) and "is 12" means equals 12.
Now, we have the equation (0.35) (x) = 12.
To solve for x, notice that x is being multiplied by 0.35 so we need to divide by 0.35 on both sides of the equation. On the left side of the equation the 0.35's will cancel and we are left with x. On the right side, we have 12 divided by 0.35 which equals 34.2857142857.
Therefore, 35% of 34.2857142857 is 12.
