Question

Order the fallowing numbers from least to greatest -3, -3.12, 1 1/2

Answer 1

Consider the following numbers:

`-3`
`-3.12`

and the mixed number:

`1(1)/(2)=\frac{(2\text{ x 1)+1}}{2}=(3)/(2)\text{ =}1.5`

now, applying the usual order of the real numbers, we have that:

`-3,12<-3<1.5`

then, the order of the given numbers from least to greatest is:

`-3.12`

`-3`

`1(1)/(2)`
