If you wanted to calculate 3175 divided by 45 could you calculate 3175divided by 5 and then divide the quotient by 9?
Yep!! TO find out first you need to calculate 3175 divided by
45(=70). Next you need to calculate 3175 divided by 5 (=635) and
then divide 635 by 9 ( = 70 .555555) so you now know that that is
one way you could do it.
