Question

russell uses 3/4 of a cup of vinegar in his salad dressing recipe. how much vinegar would russell use to make 4 1/8 recipes? write your answer as a fraction or as a whole or mixed number.

Explanation:

Step1: Convert mixed - number to improper fraction

$4\frac{1}{8}=\frac{4\times8 + 1}{8}=\frac{33}{8}$

Step2: Multiply the amount of vinegar per recipe by the number of recipes

$\frac{3}{4}\times\frac{33}{8}=\frac{3\times33}{4\times8}=\frac{99}{32}$

Step3: Convert improper fraction to mixed - number

$\frac{99}{32}=3\frac{3}{32}$

Answer:

$3\frac{3}{32}$
