Answer:
3/2
Explanation:
Total cocoa powder amount:
3/4 cup
What Brenda wants:
1/2 of the recipe.
If she wants 1/2(half) of the recipe and the full recipe calls for 3/4 cup of cocoa powder in one of its ingredients, then Brenda will have to half the amount of cocoa powder in the full recipe to find out how much she'll need of the cocoa powder for half the recipe.
Set up the equation (we are dividing the total amount of cocoa powder required in a full recipe by 2 to find out how much she'll need if she makes half the recipe and wants to find out how much cocoa powder to use then):
3/4 divided by 1/2
(When diving fractions, make the fraction you are dividing by a reciprocal and multiply the two fractions/numbers together, so):
1/2 becomes 2, and we multiply these two together:
3/4 x 2
= 6/4 which simplifies to 3/2.
The amount of cocoa powder she'll need for a recipe that is half of the original would be 3/2.
