Hello! try simplifying those two numbers so that they have the same denominators. You can see that you can convert 11/2 of flour so that you can add it with 3/4 of sugar and get the total amount together.
To convert multiply the top and bottom by 2\(\frac{11}{2} &* \frac{2}{2} = \frac{22}{4}\):
Now add across the top numbers\(\frac{3}{4} + \frac{22}{4} = \frac{25}{4}\):
And finally simplify the fraction to get your final answer. You can pull out 24 out of 25 as the common factor for 4 and 6\(\frac{25}{4}=6 \frac{1}{4}\) and the remainder will be in the numerator.
