5. a certain recipe requires 3 2/7 cups of flour and 2 3/5 cups of sugar. a) if 5/9 of the recipe is to be made, how much sugar is needed? b) if the above ingredients are required for one batch, find the amount of flour needed for a triple batch.

Given:

1 recipe requires cups of Sugar

1 recipe requires cups of Flour

In the same way,

1 Batch requires cups of Sugar

1 Batch requires cups of Flour

Solution:

If 1 recipe requires cups of Sugar, to find how much of sugar requires for recipe, we need to multiply them as below

---

If 1 Batch requires cups of Flour, to find how much of Flour requires for triple Batch, we need to multiply them as below:

Conclusion:

Part a)

Part b)

answer:

c. the third graph

the first one, all those points on the line just make a strait line.
