Section 1
Relating Division to Finding a Missing Factor
Property
Solving a division problem, such as , is the same as finding the unknown factor in the related multiplication equation, .
The quotient of the division is the unknown factor.
In this Grade 5 Pengi Math lesson, students learn to interpret division as an unknown-factor problem, connecting division equations directly to multiplication. They practice using multiplication to verify quotients and apply place value reasoning to solve division problems accurately. This lesson is part of Chapter 2: Multi-Digit Multiplication and Division with Place Value.

Relating Division to Finding a Missing Factor
Solving a division problem, such as , is the same as finding the unknown factor in the related multiplication equation, .
The quotient of the division is the unknown factor.
Section 2
Use Patterns to Divide
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:
