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.
3.875 recipes, 2.4 cups each

3.875
x 2.4
----------
1.5500
7.7500


1.55 + 7.75= 9.3 = 9 3/10 = 93/10
Yes, that's correct! Another way to solve the problem is to convert 2 2/5 to an improper fraction first, then multiply it by the number of recipes (as a mixed number or improper fraction), and simplify the result to a mixed number or whole number fraction.
