3.3.9 Equivalent Problems (Division Strategies)

3. Making an Equivalent Problem

This is similar to the way that fractions are simplified. For example, in the math problem equation left hand side 1400 division 35 equals right hand side 1400 divided by 35, both the top and bottom of the fraction can be divided by 35. You will have the opportunity to study this in Unit 6.

A division problem can be changed into an equivalent problem by dividing both numbers by the same number, thus maintaining the quotient between them.

Consider the division problem 1400 division 35.

Thus, 1400 division 35 equals 40.
