Question

Gina and 7 friends are sharing 74 pipe cleaners for an art project. What is one quick way that Gina could figure out about how many pipe cleaners each girl would get to do their art project?

a. She could think 74 is about 70, so 70 plus 8.
b. She could think 74 divided by 7.
c. She could think 74 is just over 72 and 72 divided by 8.
d. She could think 74 is about 75 and divide 75 by 8.

Answer 1

Gina can use option c: dividing 74 by 8 after approximating to 72, to quickly estimate that each person would get about 9 pipe cleaners.

Step-by-step explanation:

The fastest way Gina could estimate the number of pipe cleaners each person would get is by option c: She could think 74 is just over 72 and 72 divided by 8. 72 is a multiple of 8 that is close to 74, which makes it easier to divide. Therefore, if Gina and her friends share the pipe cleaners evenly, each would get approximately 9 pipe cleaners, since 72 divided by 8 equals 9.

The quickest way for Gina to figure out how many pipe cleaners each girl would get is by using option b, which is to divide 74 by 7.

So, 74 divided by 7 is equal to 10 remainder 4. This means that each girl would get 10 pipe cleaners, and there would be 4 remaining.
