A ratio is an ordered pair of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two ratios are specified to be equal.
Given data;
Yasemin is using a sugar cookie recipe with flour to sugar ratio of 11: 6.
For 11 units of flour 6 units of sugar are needed as;
11 cups of flour ⇒ 6 cups of sugar
1 cups flour ⇒ 6 /11 cups of sugar
1 cups flour ⇒ 0.545 cups of sugar
To make one batch of cookies, 2.75 cups of flour are needed.
If we triple the recipe then cups of flour are needed ;
⇒ 2.75 × 3
⇒ 8.75 cups
The cups of sugar needed;
⇒ 8.75 cups of flour = 8.75 × 0.545 cups of sugar
⇒8.75 cups of flour = 4.5 cups of sugar
4.5 cups of sugar are needed when the recipe is tripled.
Hence option B is correct.
