Question

$\frac{2}{9} + \frac{1}{8} - \frac{1}{6} =$
​

Answer 1

Resposta:

$\frac{2}{9}$=$\frac{2.8}{9.8}$=$\frac{16}{72}$

$\frac{1}{8}$=$\frac{1.9}{8.9}$=$\frac{9}{72}$

$\frac{1}{6}$=$\frac{1.12}{6.12}$=$\frac{12}{72}$

junta todos os resultados:

$\frac{16}{72}$+$\frac{9}{72}$-$\frac{12}{72}$=$\frac{16+9-12}{72}$

resposta:$\frac{13}{72}$

Answer 2

Resposta:

$\frac{2}{9(8)} + \frac{1}{8(9)} - \frac{1}{6(12)}$

$= \frac{18}{72} + \frac{9}{72} - \frac{12}{72}$

$= \frac{18 + 9 - 12}{72 } = \frac{15}{72}$
