Answer:
He doesn't have enough sugar.
Step-by-step explanation:
First, we need to write 1 3/4 as a fraction, so:
Then, if he made 1/3 of the recipe, he will need 1/3 of the 7/4 cups of sugar. So, 1/3 of 7/4 can be calculated as:
Now, he only had one half of a cup, and 7/12 of a cup are equivalent to:
1/2 = 0.5 cups
7/12 = 0.5833 cups
So, since 7/12 is greater than 1/2, we get that he doesn't have enough sugar.
