Answer 1

Ответ:

Пошаговое объяснение:

1)$\frac{3}{4} + \frac{3}{5} + \frac{1}{3} =\frac{3*15+3*12+1*20}{60} = \frac{45+36+20}{60}=\frac{101}{60} = 1\frac{41}{6}$

2)$\frac{2}{3} +\frac{4}{5} +\frac{2}{4} =\frac{2*20+4*12+2*15}{60} = \frac{40+48+30}{60} =\frac{118}{60} =\frac{59}{30}= 1\frac{29}{30}$

3)$\frac{2}{4} +\frac{2}{5} +\frac{2}{10} =\frac{2*5+2*4+2*2}{20} =\frac{10+8+4}{20} =\frac{22}{20} =1,1$

4) $\frac{7}{10} +\frac{2}{3}+ \frac{1}5y} =\frac{21+20+6}{30} =\frac{47}{30}$

5)$\frac{3}{4}+\frac{1}{2}+ \frac{1}{10} =\frac{15+10+2}{20} =\frac{27}{20}=1,35$

6)$\frac{8}{10}+\frac{1}{2}+\frac{2}{4} =\frac{16+10+10}{20} =\frac{36}{20} = 1,8$
