Answer 1

Ответ:

1 5/48

1 2/5

Пошаговое объяснение:

5/8-1/16=10/16-1/16=9/16

13/24+9/16=26/48+27/48=53/48=1 5/48

-------------------------------------------------------

6 1/5-4 1/3=6 3/15-4 5/15=5 18/15-4 5/15=1 13/15

1 13/15:1 1/3=28/15*3/4=7/5=1 2/5

Answer 2

$a) \frac{13}{24}+(\frac{5}{8}-\frac{1}{16})=\frac{13}{24}+(\frac{10}{16}-\frac{1}{16})=\frac{13}{24}+\frac{9}{16}=\frac{26}{48}+\frac{27}{48}=\frac{53}{48}=1\frac{5}{48}; =>b) (6\frac{1}{5}-4\frac{1}{3}):1\frac{1}{3}=(6\frac{3}{15}-4\frac{5}{15}):1\frac{1}{3}=(5\frac{18}{15}-4\frac{5}{15}):1\frac{1}{3}=1\frac{13}{15}:1\frac{1}{3}=\frac{28}{15}:\frac{4}{3}=\frac{28}{15}*\frac{3}{4}=\frac{7}{5}=1\frac{2}{5}=1,4.$
