Question

you are building a spreadsheet to calculate amounts of ingredients that will go into various recipes. you want the spreadsheet to show the conversion from cups to grams of rice flour. given that 1 cup of the flour weighs 5.6 ounces, which of the following equations will convert cups of the flour to grams?
a. grams = (number of cups) × 5.6 × 8
b. grams ≈ (number of cups) × 5.6 × 28.350
c. grams ≈ (number of cups) × 28.350 ÷ 5.6
d. grams ≈ (number of cups) × 453.592 ÷ 5.6
e. grams ≈ (number of cups) × 453.592 ÷ 16

Explanation:

Step1: Recall ounce - gram conversion

1 ounce is approximately 28.35 grams.

Step2: Determine total grams for given cups

If 1 cup of flour weighs 5.6 ounces, then for $n$ cups, the weight in ounces is $n\times5.6$ ounces. To convert this weight in ounces to grams, we multiply the number of ounces by 28.35. So the weight in grams $g$ for $n$ cups is $g=(n)\times5.6\times28.35$.

Answer:

B. grams = (number of cups) × 5.6 × 28.350
