Q

How many multiples of 4 are between 1 and 130, inclusive?

A

While you could have listed out each of the multiples of 4 between 1 and 130, recognize that there are 10 multiples of 4 between 1 and 40, 10 between 41 and 80, and 10 between 81 and 120. Between 121 and 130, there are 2 multiples of 4 (124 and 128). 128 is also the greatest multiple of 4 that is less than 130. Because 128 ÷ 4 =32, 128 is the 32nd multiple of 4.
