Question

Use a number line to compare the numbers. Which shows the correct symbol to compare the numbers? 1.2 1 1/5

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:

$1.2 = 1.2$
