Sumar 5/8a -2/3b,-3/4a+3/2b

Answer 1

$( \frac{5}{8}a - \frac{2}{3}b ) + ( - \frac{3}{4} a + \frac{3}{2}b ) = \\ \frac{5}{8} a - \frac{2}{3} b - \frac{3}{4} a + \frac{3}{2} b = \\ ( \frac{5}{8}a - \frac{3}{4} a) + ( - \frac{2}{3}b + \frac{3}{2}b ) = \\ ( \frac{5}{8} a - \frac{6}{8}a ) + ( - \frac{4}{6} + \frac{9}{6}b ) = \\ - \frac{1}{8} a + \frac{5}{6} b$
