Question

3¼+2⅚-1¾
¿cuánto es ?​

Answer 1

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

$\frac{4 \times 3 + 1}{4} + \frac{6 \times 2 + 5}{6} - \frac{4 \times 1 + 3}{4}$

$\frac{12 + 1}{4} + \frac{12 + 5}{6} - \frac{4 + 3}{4}$

$\frac{13}{4} + \frac{17}{6} - \frac{7}{4}$

$( \frac{13}{4} - \frac{7}{4} ) + \frac{17}{6}$

$\frac{6}{4} + \frac{17}{6}$

$\frac{12 \div 4 \times 6 + 12 \div 6 \times 17}{12}$

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

$\frac{18 + 34}{12}$

$\frac{52}{12} = \frac{13}{3}$
