-5 7/12+3, 9/12-2 5/12

Answer 1

To add -5 7/12 and 3 9/12, we need to first find a common denominator. The common denominator for 12 and 12 is 12.

So, -5 7/12 + 3 9/12 can be rewritten as (-5 + 3) + (7/12 + 9/12).

Working out the addition inside the parentheses, we get (-2) + (16/12).

Now, we need to simplify this addition. The fraction 16/12 can be simplified by dividing the numerator and denominator by their greatest common divisor, which in this case is 4.

So (-2) + (16/12) equals -2 + (4/3).

Since the -2 and 4/3 do not have like terms, we cannot further simplify the expression.

Therefore, -5 7/12 + 3 9/12 = -2 + 4/3.
