Question

How do i do this? Explain the answer and how it is done.

Answer 1

4/9ths of a cup of sugar is needed for one cup of flour.

Explanation:

To answer this you need to scale the number of cups of flour up from 3/4 to 1 that ratio would be 4/3 (multiplying a fraction by its own reciprocal will give you 1).

We can then simply take that ratio, and scale the sugar by the same amount:

1/3 * 4/3 = 4/9
