So basically the question is asking, what is 3/4 of 24.
You have two options:
You can covert 3/4 to a decimal (which is .75) and multiply 24 X .75
or multiply 3/4 X 24. Remember you can write 24 as 24/1.
When multiplying fractions multiply the top numbers together, then multiply the bottom numbers together. so 3/4 X 24/1 = 72/4.
Now we simply: 72/4 = 18.
