on a school trip, 56 girls and 91 boys go to south Korea they were divided into groups as possible so that each group has an equal number of girls and boy in each group, how many in each group?

Respuesta :

Answer:

21

Step-by-step explanation:

You must find a number that will divide into the total of the girls and boys and come up with an even number.  By looking at the numbers, you can see that both 56 and 91 will divide evenly by 7. The common denominator for both calculations is 7.

56/7=8 girls  

91/7= 13 boys

Add 8 girls and 13 boys and you will have 21 in each group.  That way, all groups are equally boys and girls.

8+13=21
