Question

Find the difference between the Rational numbers B and A as shown on the number line.

Answer 1

B lies between 2 and 3 and it is in the middle. Value of B = $2\frac{1}{2}$ or $\frac{5}{2}$

A lies between -1 and -2 and it is in the middle. Value of A = $-1\frac{1}{2}$ or $\frac{-3}{2}$

Difference between B and A = B - A = $\frac{5}{2}-\frac{-3}{2}$ = $\frac{5+3}{2}$ = $\frac{8}{2}$ = 4
