vă rog îmi trebuie până mâine,dau coroana​

Answer 1

a) $\frac{1}{4}+\frac{4}{5}+\frac{5}{12}+\frac{3}{20} =\frac{15}{60}+\frac{48}{60}+\frac{25}{60}+\frac{9}{60} =\frac{15+48+25+9}{60} =\frac{97}{60}$

b) $\frac{9}{8}+\frac{4}{9}+\frac{1}{36}+\frac{7}{24} =\frac{81}{72}+\frac{32}{72}+\frac{2}{72}+\frac{21}{72} =\frac{81+32+2+21}{72} =\frac{136}{72} =\frac{17}{9}$

c) $\frac{5}{8}+\frac{3}{10}+\frac{4}{5}+\frac{1}{16} =\frac{50}{80}+\frac{24}{80}+\frac{64}{80}+\frac{5}{80} =\frac{50+24+64+5}{80} =\frac{143}{80}$

d) $\frac{5}{48}+\frac{7}{16}+\frac{3}{8}+\frac{1}{32} =\frac{10}{96}+\frac{42}{96}+\frac{36}{96}+\frac{3}{96} =\frac{10+42+36+3}{96} =\frac{91}{96}$

e) $\frac{10}{9}+\frac{1}{27}+\frac{5}{18}+\frac{7}{36} =\frac{120}{108}+\frac{4}{108}+\frac{30}{108}+\frac{21}{108} =\frac{120+4+30+21}{108} =\frac{175}{108}$

f) $\frac{8}{75}+\frac{4}{15}+\frac{3}{10}+\frac{2}{25} =\frac{16}{150}+\frac{40}{150}+\frac{45}{150}+\frac{12}{150} =\frac{16+40+45+12}{150} =\frac{113}{150}$
