Multiplying Fractions Vocabulary
A ______ represents a part of a whole.
What is a Fraction
Equal.
What is Equivalent
An adjusted number that makes an operation easier to do. For example, if we were adding 498 and 342, we could add 2 to 498 to make it 500. The 2 that was added would be taken from 342, making it 340. 500 + 340 is easier to add than 498 + 342.
