Question

What number should be added or subtracted from each term in the ratio 11:9 so that it becomes 6:5?

Answer 1

Step-by-step explanation:

For added case - let x be the no added

Therefore equation will be

11+x / 9+x = 6/5

Cross multiply

5*( 11+x) = 6*(9+x)

55 + 5x = 54 + 6x

X = 1

Similar in case of subtract ion.

Answer 2

Answer:

1

Step-by-step explanation:

1+x/9+x=6/5

5(11+x)=6(9+x) [by cross multiply]

55+5x=54+6x

6x-5x=55-54

x=1
