Question

Donald builds desks. Every 8 desks require a pack of 48 screws.

Answer 1

What you want to do is 48/8 to find out how many screws needed for one desk.
48/8=6...So 6 screws for each desk
Then multiple 6*32 to find out how many screws he will need altogether.
6*32=192 screws
So Donald will need 192 screws for 32 desks

Answer 2

32/8= 4
so Donald uses the pack of 48 screws a total of 4 times to build 32 desk

48 x 4 = 192
so he used 192 screws total
