Numeros racionales
Como se hacen las siguientes operaciones de numeros racionales:
$5 \frac{2}{4}+3 \frac{5}{8} +2 \frac{1}{2} 16 \frac{3}{9}-10 \frac{5}{18} 2 \frac{4}{9} *11 \frac{2}{7} 8 \frac{3}{11} /6 \frac{4}{5} \left[\begin{array}{ccc}\\ \frac{2}{3} \\\end{array}\right] ^{4}$

Answer 1

$5 \frac{2}{4} + 3 \frac{5}{8} + 2 \frac{1}{2} =$

$\frac{5.4+2}{4} + \frac{3.8+5}{8} + \frac{2.2+1}{2} =$

$\frac{22}{4} + \frac{29}{8} + \frac{5}{2} =$

$\frac{(8:4.22) + (8:8.29) + (8:2.5)}{8} =$

$\frac{44+29+20}{8} =$

$\frac{93}{8}$



$16 \frac{3}{9} - 10 \frac{5}{18} =$

$\frac{16.9+3}{9} - \frac{10.18+5}{18} =$

$\frac{147}{9} - \frac{185}{18} =$

$\frac{18:9.147 - 18:18.185}{18} =$

$\frac{294-185}{18} =$

$\frac{109}{18}$



$2\frac{4}{9} . 11\frac{2}{7} =$

$\frac{2.9+4}{9} . \frac{11.7+2}{7} =$

$\frac{22}{9} . \frac{79}{7} =$

$\frac{22.79}{9.7} =$

$\frac{1738}{63}$



$8 \frac{3}{11} : 6 \frac{4}{5} =$

$\frac{8.11+3}{11} : \frac{6.5+4}{5} =$

$\frac{91}{11} : \frac{34}{5} =$

$\frac{91.5}{11.34} =$

$\frac{455}{374}$



$( \frac{2}{3})^{4} =$

$\frac{ 2^{4} }{3^{4} } =$

$\frac{2.2.2.2}{3.3.3.3} =$

$\frac{16}{81}$
