porfa es para hoy ayuda ​

Answer 1

vas bien pero recuerda cuando es multiplicación al vas atener que acer lo en forma de equis o mariposa y cuando son numeros con de nominadores distintos a i tienes que comprar vertirlos a igual denominador

Answer 2

Respuesta:

$\frac{5}{2} + \frac{3}{4} = \frac{10}{4} + \frac{3}{4} = \frac{13}{4}$

$\frac{2}{3} - \frac{7}{15} = \frac{10}{15} - \frac{7}{15} = \frac{3}{15} = \frac{1}{5}$

$\frac{4}{9} - \frac{1}{3} = \frac{4}{9} - \frac{3}{9} = \frac{1}{9}$

$\frac{1}{6} + \frac{4}{3} + \frac{5}{6} = \frac{1}{6} + \frac{8}{6} + \frac{5}{6} = \frac{14}{6} = \frac{7}{3}$

$\frac{5}{7} + \frac{2}{7} - \frac{1}{14} = \frac{10}{14} + \frac{4}{14} - \frac{1}{14} = \frac{13}{14}$

$\frac{5}{6} - \frac{1}{12} + \frac{4}{12} = \frac{10}{12} - \frac{1}{12} + \frac{4}{12} = \frac{13}{12}$

$3 \frac{1}{2} + \frac{1}{4} = \frac{7}{2} + \frac{1}{4} = \frac{14}{4} + \frac{1}{4} = \frac{15}{4}$

$\frac{16}{6} - 2 \frac{1}{3} = \frac{16}{6} - \frac{7}{3} = \frac{16}{6} - \frac{14}{6} = \frac{2}{6} = \frac{1}{3}$

$\frac{2}{5} + \frac{1}{3} = \frac{6}{15} + \frac{5}{15} = \frac{11}{15}$

$\frac{2}{3} - \frac{4}{7} = \frac{14}{21} - \frac{12}{21} \frac{2}{21}$

$\frac{1}{2} + \frac{1}{3} = \frac{3}{6} + \frac{2}{6} = \frac{5}{6}$

$\frac{3}{16} + \frac{3}{4} + \frac{1}{8} = \frac{3}{16} + \frac{12}{16} + \frac{2}{16} = \frac{17}{16}$

$2 \frac{5}{6} + \frac{4}{6} - \frac{1}{3} = \frac{17}{6} + \frac{4}{6} - \frac{1}{3} = \frac{17}{6} + \frac{4}{6} - \frac{2}{6} = \frac{19}{6}$

$4 \frac{2}{5} - 3 \frac{1}{10} = \frac{22}{5} - \frac{31}{ 10} = \frac{44}{10} - \frac{31}{10} = \frac{13}{10}$

$1 \frac{1}{12} - \frac{5}{6} + \frac{3}{4} = \frac{13}{12} - \frac{5}{6} + \frac{3}{4} = \frac{13}{12} - \frac{10}{12} + \frac{9}{12} = \frac{12}{12} = 1$

$\frac{2}{3} + \frac{1}{9} = \frac{6}{9} + \frac{1}{9} = \frac{7}{9}$
