When dividing or multiplying you change the mix number into a improper fraction.
2 and 1/4 --> 9/4
Then you divide it by 4 but before that rewrite 4 as and improper fraction
4 --> 4/1
And the equation looks something like this
9/4 divide by 4/1
And you keep the 9/4 and change the division sign to a multiplication sign and lastly change the 4/1 to 1/4 and cross multiply
