Multiplying & Dividing by 10, 100 & 1,000 (Mixed Review) — Easy Worksheet 2
Grade 4 · Whoobee Name: ____________________ Date: __________
Use place value and basic facts to find each missing number.
How to solve
Multiplying by 10 moves every digit one place to the left, so a zero fills the ones place: 37 × 10 = 370, 37 × 100 = 3,700 and 37 × 1,000 = 37,000. Dividing by 10, 100 or 1,000 moves the digits back to the right: 4,500 ÷ 100 = 45. For multiples of 10, multiply the basic fact, then put the zeros back: 30 × 400 is 3 × 4 = 12 with three zeros, 12,000. To divide, take the same number of zeros off both numbers first: 2,400 ÷ 60 = 240 ÷ 6 = 40.
Example
