Gabriel has 15 5/8 pounds of clay. He will use 7/10 pound to make each bowl. After making 8 bowls he wonders how many more bowls
evablogger [386]
7/10 x 8 = 5 6/10
15 5/8 - 5 6/10 = 10 1/40
10 1/40 / 7/10 = 14 9/28
so he can make 14 more bowls and 9/28 of another bowl so you round down to 14 complete bowls.
