Answer 1

Answer:

The required number is 13 which is added to each term of ratio 2:5 so that it may become equal to 5:6.

Step-by-step explanation:

To find: What must be added to each term of ratio 2:5 so that it may become equal to 5:6 ?

Solution :

Let the number to be added be 'x'.

According to question,

(2 + x): (5+ x) = 5:6

Solving,

(2+x)/(5+x) = 5/6

Cross multiply,

6(2 + x) = 5(5 + x)

12+ 6x = 25 + 5x

6x - 5x = 25 - 12

x = 13

Therefore, The required number is 13 which is added to each term of ratio 2:5 so that it may become equal to 5:6.
