Answer 1

Given : The numerator of a fraction is 3 more than its denominator.

numerator is increased by 1 and the denominator is doubled, the fraction becomes 9/10

To Find :  Fraction

Solution:

Denominator = x

Numerator = x + 3

Fraction = (x + 3)/x

numerator is increased by 1 = x + 3 + 1 = x+4

denominator is doubled = 2x

fraction becomes 9/10

=> (x + 4)/2x  = 9/10

=> 5(x + 4) = 9x

=> 5x + 20 = 9x

=> 4x = 20

=> x = 5

Fraction = (x + 3)/x = (5 + 3)/5

= 8/5
