Make teams of equal number of nine year olds and ten year olds. There are 56 9-year olds and 42 Ten year olds. How many teams can be made?

Thank you for the opportunity to help you with your question!

There are 56 9years old

and 42 10 years old

lets calculate GCF of 56 and 42

56 =2*2*2*7

42=2*3*7

GCF =2*7 =14

so team containing 14 equal numbers of nine years and ten years old can be made.

Number of nine years teams =56/14 = 4

Number of ten years teams =42/14 =3

What is the greatest number of teams that can be made so each team has an equal number?

3 or 7

Total 7 teams can be made.and that

is greatest.
