Question

me ayudan pls ???? :)​

Answer 1

Respuesta:

$\frac{13}{15} - \frac{9}{20} \\ \frac{13 \times 20 - 15 \times 9}{15 \times 20} \\ \frac{260 - 135}{300} \\ \frac{125}{300 }$

$\frac{5}{6} + \frac{2}{3} \\ \frac{5 \times 3 + 6 \times 2}{6 \times 3} \\ \frac{15 + 12}{18} \\ \frac{27}{18} \\ \frac{3}{2}$

$\frac{10}{12} + \frac{6}{3} \\ \frac{5}{6} + 2 \\ \frac{5 + 6 \times 2}{6} \\ \frac{5 + 12}{6} \\ \frac{17}{6}$
