Question

the denominator of a fraction is9 more than its numerator if the numerator and denominator both are increased by 7 the fraction become 7/10 find the original fraction​

Answer 1

Answer:

Step-by-step explanation:let the numerator be X and denominator be Y

ATQ,

y=9+x -(1)

X+7/9+x+7 = 7/10

10x+70 = 7(x+16)

10x+ 70 = 7x+112

3x = 42

X = 14

From eqn (1)

Y = 9+x

Y = 9+ 14

Y = 23
