Question

the numerator of a rational number smaller than its denominator by 4.If the numerator is increased by 3 ,and denominator is decreased by 5 the number becomes 2. Find the rational number .​

Answer 1

Hi mate I have an answer to your question

Let denominator be x then numerator is x-4

now, we have,

(x-4+3) ÷ (x+5)

(x-1)÷ (x+5) = 2

(x-1)= 2(x+5)

x-1 = 2x+ 10

2x-x= -1-10

x= -11

we have rational number = (x-4) ÷ x

= -11-4 / -11

= -15 / -11

= 15/11

Hope it helps you have a great day
