Order from least to greatest 5/18,1/4,1/6,-0.8

Answer 1

5 / 18 ,1 / 4 , 1 / 6 , - 0.8

is same as:

5 / 18 , 1 / 4 , 1 / 6 , - 8 / 10

Least common denominator is 180.

Write that fractions as:

5 / 8 = 10 ∙ 5 / 10 ∙ 18 = 50 / 180

1 / 4 = 45 ∙ 1 / 45 ∙ 4 = 45 / 180

1 / 6 = 30 ∙ 1 / 30 ∙ 6 = 30 / 180

- 8 / 10 = - 18 ∙ 8 / 18 ∙ 10 = - 144 / 180

So your numbers are:

50 / 180 , 45 / 180 , 30 / 180 , - 144 / 180

Least to greatest:

- 144 / 180 , 30 / 180 , 45 / 180 , 50 / 180

- 0.8 , 1 / 6 , 1 / 4 , 5 / 8
