Question

resta y suma de fracciones con distintos denominadores ​

Answer 1

Explicación paso a paso:

a) $\frac{3}{4}$ + $\frac{5}{8} = \frac{6}{8} + \frac{5}{8} = \frac{6+5}{8} = \frac{11}{8} = 1\frac{3}{8}$

b) $\frac{3}{4} + \frac{2}{3} = \frac{9}{12} + \frac{8}{12} = \frac{9+8}{12} = \frac{17}{12} = 1\frac{5}{12}$

c) $\frac{4}{3} - \frac{3}{5} = \frac{20}{15} - \frac{9}{15} = \frac{20-9}{15} = \frac{11}{15}$

d) $\frac{13}{8} - \frac{5}{6} = \frac{39}{24} - \frac{20}{24} = \frac{39-20}{24} = \frac{19}{24}$
