Tony separates a number of paintbrushes, x, into 3 equally sized groups. He claims that this is the same as making a group 1/3 the size of his original group. Create an equation that models Tony's claim.

Size of each group =

Step-by-step explanation:

Total number of paint brushes = x

Since each the three groups are equally sized, to get the number of paintbrushes in a group, we will have to divide the total number of paint brushes by 3

∴ We have, number of paint brushes in a group =

=

this is also the same thing as saying ×

This shows that the size of the new group is the same as the size of the original group
