Question

Sandra is cooking her famous brownies for her class. For her recipe, she needs 5/7 of a cup of sugar, and 1/8 as much salt as sugar. How much salt does she need for her recipe?

Answer 1

5/56

Explanation:

You have to multiply both numbers.

First, you have to multiply 5 & 1, that will be 5

Next, you have to multiply the denominators, which is 7 & 8, that will be 56

Finally, you put that as a fraction and get 5/56

That can not be further simplified.

Answer 2

`(5)/(56)` salt does she need for her recipe.

Explanation:

As per the statement:

For her recipe:

She needs =
`(5)/(7)` of a cup of sugar.

It is also given that: 1/8 as much salt as sugar.

⇒ She needs salt for her recipe =
`(1)/(8) \cdot (5)/(7) = (5)/(7 \cdot 8) = (5)/(56)`

Therefore,
`(5)/(56)` salt does she need for her recipe.
