Question

Subtract using the number line.

Answer 1

Given numbers -1/3 and -1 2/3.

On the number line first we plot -1/3.

We have negative numbers on left side of 0.

First number on left side of 0 is -1.

1/3 is the fraction third part of 1.

So, we need to plot a point on one third part between 0 and -1 from 0.

We need to add/subtract -1 2/3 into that -1/3 now.

We have 2/3 fraction with -1. So, we would move 2/3rd from 0 to -1.

We already at 1/3rd part between 0 and -1. The remaining part between 0 and -1 is 2/3rd part of 0 to -1.

So, moving -2/3 more to -1/3, we get exectly at -1.

And because we have -1 in front of 2/3 fracion in -1 2/3.

So, we would move one more number to left of -1 because we are exactly on -1 after moving -2/3rd of -1/3 point.

So, we would go exactly at -2.
