Question

Fracciones de suma 3/4+18=
2/6+23=
1/5+3/10

Answer 1

$\frac{3}{4} + \frac{18}{1} = \frac{3+18(4)}{4} = \frac{3+72}{4} = \frac{75}{4}$


$\frac{2}{6} +23= \frac{2}{6} + \frac{23}{1} = \frac{2+23(6)}{6} = \frac{2+138}{6} = \frac{140}{6} = \frac{70}{3}$

$\frac{1}{5} + \frac{3}{10} = \frac{1(2)+3}{10} = \frac{2+3}{10} = \frac{5}{10} = \frac{1}{2}$
