Question

What is the value of the numerical expression 5/8 - 5/12 (3 -1/4) + 2/3 ?

Answer 1

$\dfrac{5}{8} - \dfrac{5}{12} ( 3 - \dfrac{1}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{5}{12} (2\dfrac{3}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{5}{12} (\dfrac{11}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{55}{48}+ \dfrac{2}{3}$

$= \dfrac{30}{48} - \dfrac{55}{48}+ \dfrac{32}{48}$

$= \dfrac{7}{48}$
