Question

Put the numbers in order from least to greatest2.3,12/5,5/2,2.2,21/10

Answer 1

Express the fraction in terms of decimal.

`(12)/(5)=2.4`
`(5)/(2)=2.5`
`(21)/(10)=2.1`

The numbers are,

2.3, 2.4, 2.5, 2.2, 2.1.

Now we arrange the number from least to greatest.

`2.1,2.2,2.3,2.4,2.5`

So answer is,

`(21)/(10),2.2,2.3,(12)/(5),(5)/(2)`
