Anita is painting a wall in her room.
In the morninig, she painted 4%2F18 of the wall.

In the afternoon she painted 5%2F18 of the wall.

she painted altogether 4%2F18%2B5%2F18 of the wall which is %284%2B5%29%2F18=9%2F18

now, you can simplify by dividing nominator and denominator by 9
9%2F18=%289%2F9%29%2F%2818%2F9%29=1%2F2.......... she painted altogether 1%2F2 of the wall
