Question

The numerator of a rational number is 3 less than the denominator if denominator is increased by 5 and numerator by 2 we get the rational number 1 upon 2 find the rational number​

Answer 1

Step-by-step explanation:

(case1)

Numerator=d-3

Denominator =d

(case2)

Denominator=d+5

Numerator=d-1(d-3+2)

A/Q

d-1/d+5=1/2(cross multiplication )

2d-2=d+5

2d-1d=5+2

D=7

Now, rational number=7-3/7

=4/7
