Answer 1

Ответ:

1/6+1/8=4/24+3/24=7/24

5/8-1/3=15/24-8/24=7/24

2/3+3/10=20/30+9/30=29/30

11/12-3/8=22/24-9/24=13/24

Answer 2

Пошаговое объяснение:

1)

$frac{1}{6} + frac{1}{8} = frac{4}{24 } + frac{3}{24 } = frac{7}{24}$

2)

$frac{5}{8} - frac{1}{3} = frac{15}{24} - frac{8}{24} = = frac{7}{24}$

3)

$frac{2}{3} + frac{3}{10} = frac{20}{30} + frac{9}{30} = frac{29}{30}$

4)

$frac{11}{12} - frac{3}{8} = frac{22}{24} - frac{9}{24} = frac{13}{24}$
