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.
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.

1.55 + 7.75= 9.3 = 9 3/10 = 93/10
3.875

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.
