Question

Using the given number line find the difference between point A and point B :

• A. $\frac{7}{3}$
• B. $\frac{5}{3}$
• C. $\frac{2}{3}$
• D. $\frac{-5}{3}$

Answer 1

The correct option is B

$\frac{5}{3}$

In the given number Line :

Point A is at $\frac{1}{3}$

Point B is at $\frac{-4}{3}$

We can find the difference using 2 methods.

1st method : $\frac{1}{3}-\frac{-4}{3}$ = $\frac{1-(-4)}{3}$ = $\frac{1+4}{3}$ = $\frac{5}{3}$

2nd method : We can simply count the number of markings on the number line from point A to point B as there are equal markings at equal distances.

On counting we get that B is $\frac{5}{3}$ places away from A.
