Angel uses 1/8 cup of sugar for 1/3 of a recipe. How much sugar is needed if Angel makes the entire recipe twice?
umka2103 [35]

Answer:

3/4 cups of sugar

Step-by-step explanation:

So we know that 1/8 cup of sugar is for 1/3 OF a recipe.

So if we want the full recipe we jsut have to multiply 1/8 by 3 since its only worth 1/3 of the recipe.

You’ll get 3/8 cups of sugar for a whole recipe. The question asks for 2 full recipes and since we already know it takes 3/8 cups for one we can multiply that by 2 to find the amount of sugar needed for 2 full recipes.

You’d get 6/8 cups of sugar.

Simplified: 3/4
