Question

The sum of a number and 12 3/4 is 16 4/9. Find the number.

Answer 1

`x + 12 (3)/(4) = 16 (4)/(9) \\ \\ x + (51)/(4) = (148)/(9) \\ \\ x = (148)/(9) - (51)/(4) \\ \\ x = (592)/(36) - (459)/(36) \\ \\ x = (133)/(36) \\ \\ \\ x = 3 (25)/(36)`

So; the number

`3 (25)/(36)`

Answer 2

3 25/36
