<

=

>

Answer 1

For this case we must compare the following expressions:

`1.2\\1 \frac {1} {5}`

We convert the mixed number to a fraction:

`1 \frac {1} {5} = \frac {5 * 1 + 1} {5} = \frac {5 + 1} {5} = \frac {6} {5} = 1.2`

So, we have to compare:

1.2 and 1.2

It is observed that the expressions are equal, so we have the sign of equality "=":

`1.2 = 1.2`

Answer:

`1.2 = 1.2`
