Abag of apples waze seven and seven eights pounds. by weight, one 18th of the apples are rotten. what is the weight of the good apples?

7.8194 or 7 and 59/72 Pounds

To find this, take the total weight (7 and 7/8) and subtract that by the rotten weight (1/18).

You’ll need to first get a common denominator, the LCD is going to be 72 (8 x 9 and 18 x 4). Once you have these, subtract and simplify to get your final answer.

Hope this helps!
