Question

Select from the drop-down menus to correctly complete each statement. −20>−21 −19>−20 −21 is located to the of −20 on a number line. −19 is located to the of −20 on a number line.

Answer 1

−21 is located to the left of −20 on a number line.

−19 is located to the right of −20 on a number line.

Explanation:

Each number on a number line is more than the number on its left and less than the number on its right.

In other words, the smaller number lies on the left side of the larger number or larger number lies on the right side of the smaller number.

It is given that

−20 > −21

−19 > −20

It means -20 is more than -21 and -19 is more than -20.

Since -21 is less than -20, therefore −21 is located to the left of −20 on a number line.

Since -19 is more than -20, therefore −19 is located to the right of −20 on a number line.

Answer 2

left, right

Explanation:

If you use the < or ≤ symbol to compare the numbers, their left-right order is the same as on the number line. Here, we would write the ordering as ...

-21 < -20 < -19

So, we see that ...

-21 is left of -20 on the number line

-19 is right of -20 on the number line
