Question

a) $2-(1+ \frac{2}{3} )=$
b) $1-( \frac{3}{10} + \frac{5}{6} )=$

Answer 1

Respuesta:

A)

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

$2-(\frac{3}{3}+\frac{2}{3} )$

$2-(\frac{5}{3})$

$\frac{6}{3} -(\frac{5}{3})$

$\frac{1}{3}$

B)

$1-(\frac{3}{10}+\frac{5}{6} )$

$1-(\frac{9}{30}+\frac{25}{30} )$

$1-(\frac{34}{30})$

$\frac{15}{15} -\frac{17}{15}$

$-\frac{2}{15}$
