Question

“The ratio of the number of knives to the number of forks on a

table is 8:7. If there are 42 forks on the table, how many knives
are there on the table?
knives”

Answer 1

48 knives

Explanation:

The original ratio is 8:7

Our ratio now, looks like this k:42 (k is just a variable)

First, divide 42 by 7 and you'll get 6.

Multiply 6 by 8 and you'll get a product of 48.

Our new ratio should look like this 48:42

There are 48 knives.

Answer 2

48 : 42

Explanation:

1. Whatever you do to one side of the ratio you do to the other.

2. If there are 42 forks, then the ratio then looks like this: x : 42

3. One side of the ratio was multiplied by six.

4. Do the same to the other and you get 48 : 42
