there are 82 members in a band divides into 9 equal groups of 5 how many equal groups of 5 how many equal groups of 7 could be made with members that are left

The clear answer is clearly 25 is very clear to me

You need to divide 210 square inches by 35 inches and that’s going to give you 6 inches and that’s the length of the hypothenuse of the right triangle i hope that this you : )
