Answer 1

Answer:

A 3/30=x/12

Step-by-step explanation:

According to the recipe,

For 2 batches, 3 cups of flour required.

One batch has 15 mix rolls

Then 2 batches will have 2 (15) = 30 rolls

Each person gets one roll, so 3 cups of flour is required for 30 people.

The quanity of flour is proportional to the number of people.

Let x be the quantity of flour required for 12 people.
