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
