Question

Describe how to plot -3 3/4 on a number line?

Answer 1

-3 would be before the zero and the point would be on the 3.3 on the line

Answer 2

On the number line, negative numbers go to the left. Since -3 3/4 is negative, go 3 spaces to the left.

When plotting a fraction or decimal on a number line, you need to estimate. If there are half marks in between the numbers, plot the point near the half mark. If it's -3 3/4, count 3 spaces, then go to the half mark of -3 to -4, and plot the 3/4 in between the -3 and -4 half mark. If there is no half mark, place it near the -4 mark.

The red line represents the half mark, the blue line represents where the point would go. Notice how when negative, the numbers go higher as they go left.
