5/6 : 2/9 =

c) 6 : 2 1/4 =

3 1/3 : 4 1/3 =

Answer 1

A) 3 1/4 - 1 1/2 + 2 7/8 = 13/4 - 3/2 + 23/8 = 26/8 - 12/8 + 23/8 = 36/8 = 4 1/2
2 7/8 = 23/8 
21 * 1 1/14 = 21/1 * 15/14 = 315/14 = 22 1/2
1 2/5 * 3 1/3 = 7/5 * 10/3 = 70/15 = 4 10/15

b) 5/6 : 2/9 = 5/6 * 9/2 = 45/12 = 3 9/12
3/4² = 9/14
1 1/2² = 3/2² = 9/4 = 2 1/4

c) 6 : 2 1/4 = 6/1 : 9/4 = 6/1 * 4/9 = 24/9 = 2 6/9
3 3/10 : 11 = 33/10 : 11/1 = 33/10 * 1/11 = 33/110 
3 1/3 : 4 1/3 = 10/3 : 13/3 = 10/3 * 3/13 = 30/39 = 1 9/39
