Question

in a proportion the first,second,and third term is 9500,7500 and 665.What is the fourth term

Answer 1

We know that the first term and fourth term of a proportion are called extreme terms and second and the third term are called middle terms
So,let the fourth term be x
Thus 9500,7500,665,x are in proportion
product of extreme terms = 9500×x
product of middle terms = 7500×665
Since, the number make up a proportion
Therefore, 9500×x=7500×665
x=(7500×665)/9500
x=525
Therefore, the fourth term of the proportion is 525
