Question

simplifique estras expressoes , reduzindo os termors semelhantes
a) 3/8x+1/2x
b) a/2-2a/3
c) 7p-3/5p

Answer 1

$\frac{3}{8} x+ \frac{1}{2} x \\ \\ = \frac{3x+4x}{8} \\ \\ = \frac{7}{8} x$


$\frac{a}{2} - \frac{2a}{3} \\ \\ = \frac{3a-4a}{6} \\ \\ = \frac{-a}{6}$


$7p- \frac{3}{5} p \\ \\ = \frac{35p-3p}{5} \\ \\ = \frac{32}{5} p$
