Q: Tom got 40 oranges and 70 apples. If he sold 1/4 of the oranges and 1/2 of the apples. How many fruits were left in total?
A: There are 40 + 70 = 110 oranges and apples altogether . He sold 40 x .25 = 10 pieces of oranges. He sold 70 x .50 = 35 pieces of apples. So, Tom was left with 110 - 10 - 35 = 65 pieces. The answer is 65.

Q: Brenda raises mice, and her adult mice recently had three litters of 8 each. She gave a sixth of the baby mice to her friend Robbie to keep as pets. She sold three times the number of babies she gave Robbie to a pet store. Half of the remaining mice were sold to snake owners as feeder mice. How many baby mice did Brenda have left?
A:
Brenda’s mice had 3 * 8 = 24 baby mice. She gave Robbie 24 / 6 = 4 mice. Thus, she sold 3 * 4 = 12 mice to the pet store. She had 24 - 12 - 4 = 8 mice remaining. She sold 8 / 2 = 4 as feeder mice. Thus, Brenda had 8 - 4 = 4 mice left. The answer is 4.
