2/3
1) To find that out, we need to divide that 1/2 cup serving by 3/4 cup of a yogurt
![((1)/(2))/((3)/(4))=(1)/(2)*(4)/(3)=(4)/(6)\text{ =}(2)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/ii2vr8i6udwb577n675a600ipadi7gnw10.png)
When dividing fractions multiply the first by the reciprocate of the second one.
2) So, simplifying that 4/6 of the whole we can write
In a 3/4 cup of yogurt, there is 2/3 of 1/2 cup.
