Answer 2

Answer:

2/27

Step-by-step explanation:

Sum of 13/18 and 5/6 = (13+5x3)/18

                                   =>28/18=14/9

∴ Quotient x Divisor + Remainder = Dividend

⇒ 21 x Divisor= 14/9

⇒ Divisor= 14/9 x 1/21

⇒ Divisor= 2/27

∴ sum of 13/18 and 5/6 should be divided by 2/27 to get 21.
