FAQs

How do you decide which equation is true when multiplying by 10 or 100?

Verify the scale factor: multiplying by 10 shifts the value one place (adds one zero), and multiplying by 100 shifts two places (adds two zeros). Then check which choice matches that scaling.

What types of equations are included in the worksheet?

Each question gives a candidate equation in the form of a number on one side and a product using ×10 or ×100 on the other, with multiple-choice answers labeled A through D.

Where can the correct answers be found?

An answer key section provides the correct choice letter for each problem from 1 through 10.
