Answer 1

Explicación paso a paso:

$3\frac{1}{4} + 2\frac{5}{6} - 1 \frac{3}{8} \\ = \frac{(3 \times 4) + 1}{4} + \frac{(2 \times 6 )+ 5}{6} - \frac{(1 \times 8) + 3}{8} \\ = \frac{13}{4} + \frac{17}{6} - \frac{11}{8}$

luego mcm(4,6,8)= 24

$= \frac{(24 \div 4) \times 13 + (24 \div 6) \times 17 - (24 \div 8) \times 11}{24} \\ = \frac{(6) \times 13 + (4) \times 17 - (3) \times 11}{24} \\ = \frac{78 + 68 - 33}{24} \\ = \frac{113}{24} \\ = 4 \frac{17}{24}$
