Question

Solve: 8×1/2 - 3×5/8

Answer 1

8×1/2=4.

3×5/8=3.625.

Now subtract both ,
4-3.625= 0.375.

Answer 2

$8 \times \dfrac{1}{2} - 3 \times \dfrac{5}{8}$

$= \dfrac{8 \times 1}{2} - \dfrac{3 \times 5}{8}$

$= \dfrac{8}{2}- \dfrac{15}{8}$

$= \dfrac{8 \times 4}{2 \times 4}- \dfrac{15}{8}$

$= \dfrac{32}{8}- \dfrac{15}{8}$

$= \dfrac{17}{8}$

$= 2\dfrac{1}{8}$
