Question

Which set of rational numbers is arranged from least to greatest? 1 over 5, −1.4, negative 1 over 2, 3

Answer 1

`-1.4, -(1)/(2), (1)/(5), 3`

Explanation:

Given

`(1)/(5), -1.4, -(1)/(2), 3`

Required

Order from least to greatest

We have:

`(1)/(5), -1.4, -(1)/(2), 3`

Convert all fractions to decimal

`0.2, -1.4, -0.5, 3`

Now order from least to greatest

`-1.4, -0.5, 0.2, 3`

Replace fractions

`-1.4, -(1)/(2), (1)/(5), 3`
