\(\frac{9}{20}.\frac{5}{12}=\frac{45}{240}=\frac{9}{48}=\frac{3}{16}\)
\(\frac{9}{20}\)\(.\)\(\frac{5}{12}\)= \(\frac{3.3}{4.5}\)\(.\)\(\frac{5}{3.4}\)= \(\frac{3}{16}\)
\(\frac{9}{20}.\frac{5}{12}=\frac{45}{240}=\frac{9}{48}=\frac{3}{16}\)
\(\frac{9}{20}\)\(.\)\(\frac{5}{12}\)= \(\frac{3.3}{4.5}\)\(.\)\(\frac{5}{3.4}\)= \(\frac{3}{16}\)
tính thuận tiện : \(\frac{1}{12}+\frac{2}{7}+\frac{9}{12}+\frac{5}{7}+\frac{2}{12}+\frac{10}{20}+\frac{9}{20}+\frac{1}{12}=\)
tính bằng cách thuận tiện nhất
a,\(\frac{6}{7}\cdot\frac{16}{15}\cdot\frac{7}{6}\cdot\frac{21}{32}\)b, \(\frac{21}{17}\cdot\frac{13}{14}\cdot56\cdot\frac{3}{42}\) c,\(\frac{7}{4}\cdot\frac{11}{21}+\frac{11}{21}\cdot\frac{5}{4}\) d,\(\frac{23}{14}\cdot\frac{6}{14}-\frac{9}{14}\cdot\frac{6}{13}\)
Tính bằng 2 cách
a. \(\frac{5}{24}\cdot\frac{5}{12}\cdot24\)
b. \(\frac{3}{7}\cdot\frac{16}{33}+\frac{16}{33}\cdot\frac{4}{7}\)
Ai nhanh ai đúng em click nèeee
Giúp em điiiii
Tính
\(\frac{2}{5}+\frac{3}{10}-\frac{1}{2}= \)
\(\frac{8}{11}+\frac{8}{33}\cdot\frac{3}{4}=\) \(\frac{5}{12}-\frac{7}{32}:\frac{21}{16}\)
\(\frac{7}{9}\cdot\frac{3}{4}:\frac{5}{8}=\) Giải giúp mink nhé!
\(\frac{9\cdot7\cdot y}{72\cdot36}=\frac{5}{6}\)
\(\frac{1}{2}\cdot\frac{2}{3}\cdot\frac{3}{4}\cdot\frac{4}{5}\cdot...\cdot\frac{99}{100}\)
\(\frac{8}{5}\cdot\frac{4}{6}+\frac{24}{5}\cdot\frac{7}{6}+\frac{4}{5}\cdot\frac{11}{6}\cdot2\)
Tính nhanh:\(\frac{2}{3}\cdot\frac{3}{4}\cdot\frac{4}{5}\cdot\frac{5}{6}:\frac{2}{6}+2019\)
ai muốn nhận tick hông nè ?
có thì vô link và trả lời câu hỏi :
