Question

What is 3 2/3 - 1 1/4?

Answer 1

`2(5)/(12)`

Evaluate. Subtract 3 by 1

`3 - 1 = 2`

Find the least common denominators of the fractions, multiply them by the least common denominators, then subtract.

`(2 * 4)/(3 * 4) = (8)/(12)`

`(1 * 3)/(4 * 3) = (3)/(12)`

Now subtract.

`(8)/(12) - (3)/(12) = (5)/(12)`

Add the whole number you found earlier from subtracting 3 and 1 by the new fraction, 5/12

`2 + (5)/(12) = 2(5)/(12)`
