Question

Order these from least to greatest 3 39/40 , 3 19/20 , 3 1/2

Answer 1

Hey!

First change all the fractions so that they have a common denominator: 40

`3 (39)/(40) = 3 (39)/(40)`

`3 (19 * 2)/(20 * 2) = 3 (38)/(40)`

`3 (1 * 20)/(2 * 20) = 3 (20)/(40)`

Now order them:

`3 (39)/(40) , 3 (19)/(20) , 3 (1)/(2)`

Good luck and hope this helps! :)
