Simplify your answer and write it as a fraction or as a whole or mixed number.
cups
what is the answer to this
To find the answer, you need to multiply the amount of vinegar used in one recipe by the number of recipes.
2 2/5 cups x 3 7/8 =
To make this calculation easier, you can convert the mixed numbers to improper fractions:
2 2/5 = 12/5
3 7/8 = 31/8
Now let's multiply:
12/5 x 31/8 = 372/40
To simplify the fraction, you can divide both the numerator and denominator by their greatest common factor, which is 4:
372/40 = 93/10
Therefore, Hugo would use 93/10 cups (or 9 3/10 cups) of vinegar to make 3 7/8 recipes.
