Flour:Water:Sugar = 7:4:1

Flour:Water = 7:4
New Ratio of Flour:Water = 14:4 = 7:2 (Multiplying the ratio by 2)

Flour:Sugar = 7:1
New Ratio of Flour:Sugar = 7:2 (Halving the ratio)

New Ratio of Flour:Water:Sugar = 7:2:2

For every 2 cups of water, there is 2 cups of sugar. IF you have 8 cups of water, you need 8 cups of sugar.

Hello,

Flour/Water = 7/4, Flour/Sugar = 7/1

Double the ratio of Flour/Water = 7/4 * 2 = 7/2

Halve the ratio of Flour to Sugar = 7 * 1/2 = 7/2

The new ratio of Flour: Water: Sugar = 7:2:2

For 8 cups of water in the new recipe, sugar required will be 8 cups.

Answer is C

Hope this helps :)

I am not sure I follow you.

Original Ratio of Flour:Water = 7:4 = \frac{7}{4}
New Ratio of Flour:Water (original will be doubled) = \frac{7}{4}*2 = \frac{14}{4}

Thereafter, I brought 14/4 to lowest terms 7/2.

Original Ratio of Flour:Sugar = 7:1 = \frac{7}{1}
New Ratio of Flour:Sugar (original will be halved) = \frac{7}{1*2} = \frac{7}{2}
