is -13/26 less than -21/30

Question

In order from least to greatest: 6, -13/26, -21/30, 16/20

Answer 1

Hopefully you know that -13/26 = -1/2. Half of 30 is 15, so -15/30 = - 1/2.

 

21/30 > 1/2, but we're dealing with negative numbers, so -21/30 < -1/2, just like -3 < -2.

 

So, the order is -21/30, -13/26, 16/20, 6.
