Answer 1

The numbers are 1.3, 7/5, and 1 4/5.
First, can you write 7/5 and 1 4/5 as decimals?
Use a calculator to do the divisions.

7/5 as a decimal is 1.4
1 4/5 as a decimal is 1.8

Answer 3

Correct.
Now look at the number line I drew above.
How long is each space between marks?

Answer 4

d.
{ 1.3, 7/5, 1+4/5 } = { 1.3, 1.4, 1.8 }

Answer 5

The numbers at the ends are 1 and 2.
That means you have 1 unit between the marks labeled 1 and 2.
How many spaces are there between 1 and 2?
