Explanation:
The question here says that Dana is making bean soup the recipe she has makes 10 serving and uses 3/4of a pound of beans. How many total pounds of beans does she need to make 5 serving of soup? She has 1/10 of a beans in one contanier and 1/4 of a pound of beans in another container. How many more pounds of beans does Dana need to make the 5 serving of soup?
If 10 servings of soup makes use of 3/4 pound of beans,5 servings of soup will make use of :
10/5 = 0.75/x
X = (0.75 × 5) ÷ 10
X = 3/8 pounds of beans
I/4 pound of beans is in one container and 1/10 pound of beans is in another container ie
1/10 + 1/4 = 7/20 pound of beans is available to her,but she needs up to 3/8.
The remaining amount of bean is
3/8 - 7/20
= 1/40 pounds of beans
