Multiplying by 10, 100 & 1,000 — Easy Worksheet 2
Grade 4 · MathSheets Name: ____________________ Date: __________
Multiply. Count the zeros in 10, 100 or 1,000. The same kind of fact comes in different shapes.
How to solve
Multiplying by 10 moves every digit one place to the left, so a 0 fills the ones place: 47 × 10 = 470. Multiplying by 100 adds two zeros (47 × 100 = 4,700) and by 1,000 adds three zeros (47 × 1,000 = 47,000). Zeros already in the number stay: 450 × 100 = 45,000 and 305 × 10 = 3,050. For a missing factor, count how many zeros were added: 36 × ___ = 36,000 needs 1,000.
Example
3 × 10 = ___
Answer: 30
