Question

what sum would you do to work this out.. 3 3/4 is bigger than 1 19/21 How many times bigger

Answer 1

If the question is "how much larger" a number is than another number, you subtract the numbers.
If the question is "how many times larger" a number is than another number, you divide one number by the other.
In neither case do you add the numbers.

Answer 2

so do you divide in this sum or subtract

Answer 3

If you are answering this question:
"3 3/4 is bigger than 1 19/21 How many times bigger ?",
then divide 3 3/4 by 1 19/21.
The way to do that division is to first convert each mixed numeral into a fraction. Then divide the fractions by multiplying the first fraction by the reciprocal of the second fraction.
