What has to be added to the sum of 2/3 & 3/2 to get 3? give answer as whole number or fraction < question 10 in the image>

Be x that has to be added to the sum of 2/3 and 3/2
(2/3+3/2)+x=3

Solving for x:
(2*2+3*3)/6+x=3
(4+9)/6+x=3
13/6+x=3
13/6+x-13/6=3-13/6
x=(6*3-13)/6
x=(18-13)/6
x=5/6

5/6 has to be added to the sum of 2/3 and 3/2 to get 3

Aso sorry if i’m wrong
