Answer 2

Given:

We have given numbers which are in proportion 254:436::730:?

To Find:

We have to find the fourth proportion number?

Step-by-step explanation:

       Proportion:

• Proportion means it is set of two equal ratios. We say numbers are in proportion which the ratio of these numbers are equal

• If numbers are in proportion we can say the product of extreme terms must be equal to product of mean terms

• We have given proportion which is written as

       254:436::730:?

• Where first terms is 254 ,Second term is 436, Third term is 730 We have to find the fourth term

• Since product of extreme terms= Product of mean terms

       Let the fourth terms be x.

       $254\times x=730\times436$

       Now simplify the above equation we get

       $254x=318280\\x=\frac{318280}{254} =\frac{159140}{127}$
