Question

please help me to solve it​

Answer 1

Answer:

Now A/Q

=>x+7/x+7-5= 12/7

=>x+7/x+2= 12/7

=>7(x+7) = 12(x+2)

=> 7x+49= 12x +24

=> 7x -12x = 24-49

=> -5x = -25

=> 5x = 25

So, x= 25/5 = 5

Now the rational number will be

x/x+7 = 5/12

Answer 2

Answer:

Step-by-step explanation:

let the fraction be $\frac{p}{q}$

so q = p + 7

$\frac{p+7}{q-5} = \frac{12}{7}$

$\frac{p+7}{p+7-5} =\frac{12}{7}$

$\frac{p+7}{p+2}=\frac{12}{7}$

$7p+14=12p+24$

$12p-7p=24-14$

$5p=10$

p=$\frac{10}{5}$

$p=2$
