Back

It means that the first quantity is multiplied by x to get the second quantity.

Front

How can you express a relationship where one quantity is half of another?

Back

You can express it as 'the first quantity is 0.5 times the second quantity' or 'the second quantity is 2 times the first quantity'.

Front

What is the first step in solving a multiplicative comparison problem?

Back

Identify the quantities being compared and determine the multiplier (how many times one quantity is compared to the other).
