Ниже

Пошаговое объяснение:

11/30+3/4=22/60+45/60=67/60=1 7/60

11/65+2/13=11/65+10/65=21/65

6/10+2/5=6/10+4/10=10/10=1

1/5+17/20=4/20+17/20=21/20=1 1/20

3/10+3/4=6/20+15/20=21/20=1 1/20

Answer 2

Пошаговое объяснение:

$\frac{11}{30} + \frac{3}{4} = \frac{22 + 45}{60} = \frac{67}{60} = 1 \frac{7}{60}$

$\frac{11}{65} + \frac{2}{13} = \frac{11 + 10}{65} = \frac{21}{65}$

$\frac{6}{10} + \frac{2}{5} = \frac{3}{5} + \frac{2}{5} = \frac{3 + 2}{5} = \frac{5}{5} = 1$

$\frac{1}{5} + \frac{17}{20} = \frac{4 + 17}{20} = \frac{21}{20} = 1 \frac{1}{20} = 1.05$

$\frac{3}{10} + \frac{3}{4} = \frac{6 + 15}{20} = \frac{21}{20} = 1 \frac{1}{20} = 1.05$
