Question

Is the following a proportion?

2/3 and 10/20

A) Proportion

B) Not a proportion

Answer 1

Answer: B) Not a proportion

Explanation:

By definition, a proportion indicates that two fractions or two ratios are equal.

Therefore, keeping the definition above on mind, you must divide the numerator by the denominator of each fraction. If the result is the same, it is a proportion, if it is not the same, then it is not a proportion:

`(2)/(3)=(10)/(20)\\\\\0.66=0.5`

It is not a proportion.

Answer 2

B) Not a proportion

Explanation:

Proportion means, they are in equal ratio.

2/3 = 10/20

We have to cross multiply them and see if they are equal.

2*20 = 10*3

40 = 30

This is not true.

Therefore, they are not a proportion.

Hope this will helpful.
