Question

1. What is 2/5 7/7 10/9 smallest to greatest.

Answer 1

2/5 = 0.4                     7/7 = 1                            10/9 = 1.111111111111111111111
So from smallest to greatest is 2/5, 7/7, 10/9

1/10 = 0.1                   1/3 = 0.3333333333        1/2 = 0.5
So from  smallest to greatest is 1/10, 1/3, 1/2

Answer 2

The first one is already from smallest to greatest because 
2/5 = 0.4 , 7/7 = 1 , and 10/9 = 1.111

The second one is already in order too because 1/10 = 0.1 , 1/3 = 0.333 , and 1/2 = 0.5
