a ) \(3\frac{4}{5}-2\frac{3}{4}:1\frac{1}{8}=\frac{19}{5}-\frac{11}{4}:\frac{9}{8}=\frac{19}{5}-\frac{22}{9}=\frac{61}{45}\)
b ) \(4\frac{5}{7}:1\frac{5}{6}+2\frac{7}{15}.\frac{21}{74}=\frac{33}{7}:\frac{11}{6}+\frac{37}{15}.\frac{21}{74}=\frac{18}{7}+\frac{7}{10}=\frac{229}{70}\)
tính
a) \(3\frac{4}{5}-2\frac{3}{4}:1\frac{1}{8}=????\)
b) \(4\frac{5}{7}:1\frac{5}{6}+2\frac{7}{15}x\frac{21}{74}=???????\)
tính
a) \(3\frac{4}{5}-2\frac{3}{4}:1\frac{1}{8}=????\)
b) \(4\frac{5}{7}:1\frac{5}{6}+2\frac{7}{15}x\frac{21}{74}=???????\)
Bài 1:
a) 3\(\frac{4}{5}\)- 2\(\frac{3}{4}\): 1\(\frac{1}{8}\)=
b) 4\(\frac{5}{7}\): 1\(\frac{5}{6}\)+ 2\(\frac{7}{15}\)* \(\frac{21}{74}\)=
So sánh:\(\frac{\frac{\frac{1}{2}}{\frac{3}{4}}}{\frac{\frac{5}{6}}{\frac{7}{8}}}+\frac{\frac{\frac{8}{7}}{\frac{6}{5}}}{\frac{\frac{4}{3}}{\frac{2}{1}}}\) và\(\frac{\frac{\frac{1}{2}}{\frac{3}{4}}+\frac{\frac{8}{7}}{\frac{6}{5}}}{\frac{\frac{5}{6}}{\frac{7}{8}}+\frac{\frac{4}{3}}{\frac{2}{1}}}\)và \(\frac{\frac{\frac{1}{2}+\frac{8}{7}}{\frac{3}{4}+\frac{6}{5}}}{\frac{\frac{5}{6}+\frac{4}{3}}{\frac{7}{8}+\frac{2}{1}}}\)và\(\frac{\frac{\frac{1+8}{2+7}}{\frac{3+6}{4+5}}}{\frac{5+4}{\frac{6+3}{2+1}}}\)
