Clayton has two identical water bottles. One is 2/6 full and the other is 3/6 full. He says he has 5/12 of a bottle in all. Is Clayton’s answer correct?

• Yes

• No

Answer explanation

Clayton has 2/6 + 3/6 = 5/6. Since 1/6 = 2/12, we would multiply 5/6 by 2 and get 10/12. Clayton has 10/12 of a bottle in all, not 5/12.
