Question

Where would you put the decimal point in 201 x 15 to make it equal 30.15

201 x 15 = 30.15

Answer 1

201 changes to 2.01 or 15 changes to 0.15

2.01 · 15 = 30.15

201 · 0.15 = 30.15

Explanation:

Since 201 · 15 = 3015, and we want 30.15

We move the decimal two place to the left.

Since we did this on one side of the equation, we must do it on the other as well.

201 becomes 2.01. You could also change 15

15 becomes 0.15

Answer 2

2.01 x 15 = 30.15

Explanation:

2.01 x 15 = 30.15

or

201 * .15 = 30.15
