Answer:
.
Step-by-step explanation:
Let the unknown fraction be
,
where, x and y both are prime numbers less than 20.
Now, it is given that adding 1 to both numerator and denominator will make the fraction
.
Thus,
= 
2(x + 1) = y + 1
2x + 2 = y + 1
2x + 1 = y.
Clearly if x will be any odd number , two times x will be odd and adding 1 to it will result in even number and y should be even number , which is not possible as only even prime is 2.
Thus , x should be the even prime which is 2.
And y will be 5.
Thus the required fraction is
.

Answer:
12a + 18b
Discussion:
The question asks us to calculate
24a + 10 b - (12a - 8b) => (combine common terms)
(24a - 12a) + ( 10b + 8b) => ( as - (-8b) = + 8b)
12a + 18b
