Answer 2

Answer:

$-0.9$ is 1.3 units left from 0.4 on a number line.

$1.7$ is 1.3 units right from 0.4 on a number line.

Step-by-step explanation:

We are asked to find the numbers that are 1.3 units from 0.4 on a number line.

We know that number to the left of 0 are negative numbers and number to the right of 0 are positive on number line.

The number 1.3 units to the left of 0.4 on the number would be $0.4-1.3=-0.9$.

Therefore, $-0.9$ is 1.3 units left from 0.4 on a number line.

The number 1.3 units to the right of 0.4 on the number would be $0.4+1.3=1.7$.

Therefore, $1.7$ is 1.3 units right from 0.4 on a number line.
