Answer:

3/8

Step-by-step explanation:

a + b =12

a x b = 24

factors of 24 = 1 , 2 , 3, 4 , 6 , 8 , 12 , 24

out of these 4 and 8 add to make 12

so the reciprocals of 4 and 8 are 1/4 and 1/8

1/4 + 1/8 = 3/8

10/24
A+B= 12
AB =24
A= 24/B
Putting this value in
24/+ B=12
On solving this A= 4 and B= 6
So reciprocal is 1/4+ 1/6=4+6/24
=10/24
