Answer 1

The given ratio is 4 parts of plain flour to 1 part of cornstarch.

So, each recipe with the same ratio will be the answer.

As you can observe, the first choice is proportional because the plain flour is 4 times the cornstarch.

The second choice is proportional too because the plain flour is 4 times the cornstarch.

However, the last choice is not proportional because it has a ratio of double, which is not correct.
