Question

Sabendo que W = (+ 1/4) + (- 3/2) e K = (-5/3) - (-3/4) , então o valor de W + k é

Answer 1

$W=(+\frac{1}{4})+(-\frac{3}{2})$

$W=\frac{1}{4}-\frac{3}{2}$

$W=\frac{1}{4}-\frac{6}{4}$

$W=-\frac{5}{4}$

$K=(-\frac{5}{3})-(-\frac{3}{4})$

$K=-\frac{5}{3}+\frac{3}{4}$

$K=-\frac{20}{12}+\frac{9}{12}$

$K=-\frac{11}{12}$

$W+K=(-\frac{5}{4})+(-\frac{11}{12})$

$W+K=-\frac{5}{4}-\frac{11}{12}$

$W+K=-\frac{15}{12}-\frac{11}{12}$

$W+K=-\frac{26}{12}$

$W+K=-\frac{13}{6}$
