Nine times Here are 10 sets of 5. How many cubes is that?
Nine times I know! 10 x 5 = 50.
So how would I change this to get 9 x 5? Nine times So how would I change this to get 9 x 5?
Nine times Take off one set of 5. So 9 x 5 = 45.
Nine times Here are 10 sets of 7. How many cubes is that?
Nine times I know! 10 x 7 = 70.
So how would I change this to get 9 x 7 ? Nine times So how would I change this to get 9 x 7 ?
Nine times Take off one set of 7. So 9 x 7 = 63.
