40 because the three in the units place is smaller than 5 so you round down.
The compatible numbers are 5220 and 60 because 522/6 = 87
I GUESS I AM RIGHT AND I REALLY HOPE THIS HELPS!!!!
Cartlita is right because 60 inches is 5 feet.
Im going to take a guess and say zero because any number times zero is zero.
8 / 86 = 12 / x
cross multiply
(8)(x) = (86)(12)
8x = 1032
x = 1032/8
x = 129 pieces
