turn 2 1/4 into an improper fraction: 2 1/4 = 9/4

now you have 9/4 divided by 3/4

to divide 2 fractions invert the 2nd fraction and multiply
so change 9/4 / 3/4 to 9/4 x 4/3
now multiply the 2 top numbers and then the 2 bottom numbers:

9 *4 = 36
4 * 3 = 12

so you have 36/12 which = 3

so 2 1/4 / 3/4 = 3
