Question

Mr. Ellis runs an after-school program for 6th

and 7th graders. One afternoon, 56 6th
graders and 42 7th graders attend the after
school program. What is the greatest number
of teams Mr. Ellis can make so each team
has the same number of 6th graders and the
same number of 7th graders?

Answer 1

Each team should have 7 students.

Explanation:

To make each team having the same number of sixth graders and seventh graders, we have to find the HCF.

To find HCF, prime factorize 42 and 46.

42 = 2 * 3 * 7

56 = 2 * 2 * 2 * 7

HCF = 7

Answer:

Each team should have 7 students.
