21/18
First find a number that goes into both the numerator and denominator. 3 goes into both 21 and 18, so we'll use that.

21 ÷ 3 = 7

18 ÷ 3 = 9

7/9

There is nothing other than 1 that goes into both 7 and 9 evenly, so this is the simplest it gets.

21/18 simplified is 7/9

21/18 simplified is 1 1/6. 18 goes into 21 one time with 3 remaining. 3/18 can be simplified leaving you with 1/6. Add the whole number and you get:
1 1/6
