\(\frac{7,9-14}{3-17}=\frac{-6,1}{-14}=\frac{61}{140}\)
\(\frac{7,9-14}{3-17}\)= \(\frac{-6,1}{-14}\)= \(\frac{4}{35}\)
\(\frac{7,9-14}{3-17}=\frac{-6,1}{-14}=\frac{61}{140}\)
\(\frac{7,9-14}{3-17}\)= \(\frac{-6,1}{-14}\)= \(\frac{4}{35}\)
7,9-14/3-17 giúp mik với đang ôn thi ạ
tính
\(\frac{3}{14}x\frac{5}{17}+\frac{11}{14}x\frac{5}{17}+\frac{12}{17}x\frac{5}{16}+\frac{12}{17}x\frac{11}{16}\)
\(A=\frac{3}{15}\times\frac{5}{9}\div\frac{-18}{17}\times\frac{14}{17}\)
a) \(3\frac{14}{19}+\frac{13}{17}+\frac{35}{43}+6\)
b) \(\frac{\frac{15}{12}+\frac{3}{4}-1}{3-\frac{5}{6}+\frac{2}{3}}+\frac{\frac{16}{5}+\frac{16}{7}-\frac{16}{9}}{\frac{17}{5}+\frac{17}{7}-\frac{17}{9}}\)
\(\frac{5}{9}.\frac{14}{17}+\frac{1}{17}.\frac{5}{9}+\frac{2}{9}.\frac{5}{17}\)
\(\frac{7.9-14}{3-17}\)=?
Tính HƠPJ LÝ
a> \(\frac{11}{125}-\frac{17}{18}-\frac{5}{7}+\frac{4}{9}+\frac{17}{14}\)
b>\(\left(6-\frac{2}{3}+\frac{1}{2}\right)-\left(5+\frac{5}{3}-\frac{3}{2}\right)-\left(3-\frac{7}{3}+\frac{5}{2}\right)\)
__CÒN NỮA
Tính hợp lý:
a) \(\frac{11}{125}-\frac{17}{18}-\frac{5}{7}+\frac{4}{9}+\frac{17}{14}\)
b)\(1-\frac{1}{2}+2-\frac{2}{3}+3-\frac{3}{4}+4-\frac{1}{4}-3-\frac{1}{3}-2-\frac{1}{2}-1\)
Giúp mình với!!!
Bài 1 : Thực hiện phép tính hợp lý (nếu có thể)
\(b.\frac{1}{125}-\frac{17}{18}-\frac{5}{7}+\frac{4}{9}+\frac{17}{14}\)
\(c.1-\frac{1}{2}+2-\frac{2}{3}+3-\frac{3}{4}+4-\frac{1}{4}-3-\frac{1}{3}-2-\frac{1}{2}-1\)
