Question

French cooks usually weigh ingredients. A French recipe uses 225 grams of granulated sugar.How many cups are needed if there are 2 cups of sugar per pound: (Note that you are changingfrom units of weight, grams, to units of volume, cups. There are 453.5 grams/pound)cups

Answer 1

Given:

The amount of granulated sugar used fo French fries, x=225 g.

1 pound=2cups.

1 pound=453.5g.

Since 1 pound =453.5 g,

`1\text{ g=}(1)/(453.5)\text{ pound}`

Therefore, 225 grams can be expressed in pound as,

`\begin{gathered} 225\text{ g=}225\text{ g}*\frac{(1)/(453.5)pound}{1\text{ g}} \\ =(225)/(453.5)pound \\ \cong0.496\text{ pound} \end{gathered}`

Since 1 pound =2 cups, we can write

`\begin{gathered} 0.496pound=0.496pound*\frac{2cup}{1\text{ pound}} \\ =0.992\text{ cups} \\ \cong1\text{ cup} \end{gathered}`

Therefore, 1 cup is needed.
