1: You can make the numbers into improper fractions like so:
e.g.

2 2/3 - 1 3/4= 8/3 x 7/4

Then you make them equivalent fractions, via multiplying the denminators with eachother, and doing the same with the numerators.

32/12 - 21/12

Then you just do subtraction normally.

32/12 - 21/12= 11/12

You can also carry over from the whole number. But first, make them equivalent.

2 2/3 - 3/4= 2 8/12 - 9/12=

Then you carry over from the whole number and subtract.

1 20/12 - 9/12= 1 11/12
