Question

Three letters weigh 1/2 ounces 1/4 ounces and 7/12 ounces what is the total weight of the letters simply your answer

Answer 1

7/6

Explanation:

You might change 1/2 to 6/12, 1/4 to 3/12, and you wouldn't change 5/12. So your choice is to add them all together to get 14/12 which you can simplify to 7/6.
