Use Patterns to Divide
Property
When you multiply or divide both the dividend and the divisor by the same number (except zero), the quotient does not change. For multiples of 10, this pattern can be shown as:
In this Grade 5 lesson from enVision Mathematics, students learn to use place value patterns and basic multiplication facts to mentally divide multiples of 10, such as finding quotients like 18,000 ÷ 90 by relating them to the basic fact 18 ÷ 9. The lesson covers dividing with multiples of 10 up to five-digit dividends and two-digit divisors using mental math strategies. It is part of Chapter 5, which focuses on models and strategies for dividing whole numbers.

Section 2
Strategy: Divide Multiples of 10 by Multiples of 10
To divide multiples of 10, you can simplify the problem by dividing both the dividend and the divisor by 10. This pattern allows you to use a basic division fact.
