Of 96 oranges, half were ripe. If 1/4 of the ripe oranges were eaten and 1/8 of the unripe oranges were eaten, how many were left eaten in total?
A step-by-step solution is:
78
There were 96 / 2 = 48 ripe oranges.

48 / 4 = 12 ripe oranges were eaten.

48 / 8 = 6 unripe oranges were eaten.

There were 12 + 6 = 18 oranges eaten in total.

There were 96 - 18 = 78 oranges left uneaten.

.

Thus, the answer is 78
