Answer 2

Concept:

Ratio:

It is a comparison of two quantities.

Proportion:

It means that there is an equality of two ratios.

Given:

We are given that:

2 : 12 :: ? : 80

Find:

We need to find the missing number.

Step-by-step explanation:

We first need to let the missing number be x.

2 : 12 :: x : 80

Since, we know that proportion is an equality of two ratios, we get that:

2 / 12 = x / 80

1 / 6 = x / 80

80 = 6 x

x = 80 / 6

x = 40 / 3.

Therefore, we get the value of missing number as 40 / 3.
