Answer 1

Explicación paso a paso:

$\frac{8}{10} + \frac{4}{5} = \frac{8}{10} + \frac{8}{10} = \frac{80}{10} = 8$

$\frac{5}{3} + \frac{1}{4} = \frac{(5 \times 4) + (3 \times 1)}{3 \times 4} = \frac{20 + 3}{12} = \frac{23}{12} = 1.91666666$

$\frac{16}{8} + \frac{3}{6} = \frac{(16 \times 6 )+ (8 \times 3)}{8 \times 6} = \frac{96 + 24}{48} = \frac{120}{48} = \frac{5}{2} = 2.5$

$\frac{21}{5} - \frac{3}{10} = \frac{42}{10} - \frac{3}{10} = \frac{42 - 3}{10} = \frac{ 39}{10} = 3.9$

$\frac{9}{2} - \frac{5}{4} = \frac{18}{4} - \frac{5}{4} = \frac{18 - 5}{4} = \frac{13}{4} = 3.25$

$\frac{6}{6} - \frac{9}{10} = \frac{(6 \times 10) - ( 6 \times 9)}{6 \times 10} = \frac{60 - 54}{60} = \frac{6}{60} = \frac{1}{10} = 0.1$

$\frac{1}{2} \times \frac{3}{4} = \frac{1 \times 3}{2 \times 4} = \frac{3}{8} = 0.375$

$\frac{5}{6} \times \frac{3}{3} = \frac{5 \times 3}{6 \times 3} = \frac{15}{18} = \frac{5}{6} = 0.83333333$
