Question

the sum of numerator and denominator is 15.rhe denominator is 3 more than twice the numerator than what is the fraction​

Answer 1

Answer:

4/11

Step-by-step explanation:

Let the numerator be x.

Given that the sum of the numerator and denominator is 15.

Hence, denominator = 15-x

According to Question,

15-x = 2x+3

=> 15-3 = 2x+x

=> 12 = 3x

=> x = 4

Hence, numerator = 4

Denominator = 15-4 = 11

Therefore, the fraction is 4/11.

Answer 2

Answer:

Let the numerator be x and denominator be y

let the fraction be x/y

x + y + 3 = 2y

(or) x - y = -3

(or) x = y -3 _____(1)

Also, x-1/y-1

x-1 = y-1/2

x= y-1/2 + 1 => 2x = 2x = y - 1 + 2 = y+1

(or) 2x - y = 1 _____ (2)

Substituting (1) in (2)

2(y-3) - y = 1

=> 2y-6 - y = 1 => y = 7

put y = 7 in (1) we get x=7 -3 =4

• x=3

y=7

•the fraction is = x/y = 4/7

● 4/7 ●

y=
