Answer 1

The ratios to this would be:

`\left[\begin{array}{ccc}2&24\\6&72\\9&108\end{array}\right]`

Explanation:

Ratios are similar to fractions, in some ways, ratios are to show the relation between two numbers, such like a proportion:

For example:

4:3

or the ratio of men' jobs to women's' is 8 to 1 (8:1)

In this case, it is said that:

Gary needs 24 screws for every 2 chairs.

The ratio of this is 24: 2

Also meaning:

`(24)/(2)`

and
`2√(24)`, the quotient is = 13

Now we multiply 12 to '6' and '9'

You will get:

12(6) = 72

12(9) = 108

This will be your answer.

Answer 2

For 6 chairs, 72 screws and for 9 chairs, 108 screws.

Explanation:

So, for every 2 chairs, he needs 24 screws.

By Unitary Method,

We get screws needed for one chair, that is, 24/2 = 12 screws for one chair.

So, for 6 chairs,

6 × 12 = 72 screws.

Similarly, for 9 chairs,

9 × 12 = 108 screws.
