a recipe requires 5/6 cups of sugar. if mrs.marina is going to make one half of the recipe, how much sugar does she need?

(1/2) * (5/6) = 5/12

5x(1/2) is 2.5, so it's 2.5/6 or you can multiply it by 2 to get whole numbers= 5/12

4/6

To find out how much sugar Mrs. Marina needs for half of the recipe, we need to multiply the amount of sugar required for the full recipe by one half.

First, let's calculate the amount of sugar needed for the full recipe:
5/6 cups of sugar

Now, multiply this by one half to find the amount needed for half of the recipe:
(5/6) * (1/2)

To multiply fractions, we multiply the numerators (top numbers) together and the denominators (bottom numbers) together:
(5 * 1) / (6 * 2)

Simplifying, we get:
5/12 cups of sugar

Therefore, Mrs. Marina needs 5/12 cups of sugar for half of the recipe.
