Answer:
13/7
Step-by-step explanation:
let the denominator be x
and numerator be x+6.
so the rational number is x+6/x
now as given
x+6+7/x+1= x+13/x+1
but given is 5/2
so x+13/x+1=5/2
so we will do cross multiplication
2(x+13)=5(x+1)
2x+26=5x+5
2x-5x=5-26 (transposing)
-3x=-21 (we will cut minus from both sides)
x = 21/3 = 7
so the rational number
= x+6/x=7+6/7=13/7

Answer:
x+6 DINOMINATOR
X NUMERATOR
Step-by-step explanation:
X +8
X+6+8=x+14
x+8=5
x+14=2
cross multiplication
5(x+14)=2(x+8)
5x+70=2x+16
5x - 2x =70- 16
3x=54
x=18
x+6=18+6=24
