Answer 1

2.3
2 4/5= 2.8
3.01
3.017

4 1/8= 4.125
4.2

Answer 2

2.3, 2.8, 3.01, 3.017, 3.10, 4.125, 4.2

Or
`2.3, 2(4)/(5), 3.01, 3.017, 3.10, 4(1)/(8), 4.2`

Explanation:

The given numbers are
`4.2, 3.10, 4(1)/(8), 3.01, 2.3, 2(4)/(5), 3.017`

To arrange them we will covert the fractions into decimals first.

`4.2, 3.10, 4.125, 3.01, 2.3, 2.8, 3.017`

Let's understand which number is greater among 2.3 and 2.8.

Here 2 is common in both the numbers but after decimal one number has 2 and other 8.

So number having greater number after decimal will be greater than the other one.

Therefore, out of 2.3 and 2.8, 2.8 will be greater.

Now we will arrange all the numbers from least to greatest.

2.3, 2.8, 3.01, 3.017, 3.10, 4.125, 4.2
