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

Respuesta :

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,

[tex]1\text{ g=}\frac{1}{453.5}\text{ pound}[/tex]

Therefore, 225 grams can be expressed in pound as,

[tex]\begin{gathered} 225\text{ g=}225\text{ g}\times\frac{\frac{1}{453.5}pound}{1\text{ g}} \\ =\frac{225}{453.5}pound \\ \cong0.496\text{ pound} \end{gathered}[/tex]

Since 1 pound =2 cups, we can write

[tex]\begin{gathered} 0.496pound=0.496pound\times\frac{2cup}{1\text{ pound}} \\ =0.992\text{ cups} \\ \cong1\text{ cup} \end{gathered}[/tex]

Therefore, 1 cup is needed.
