a. 1\(-\left(5\frac{3}{8}+y-7\frac{5}{24}\right)\div16\frac{2}{3}=0\) 0
b. \(y\times6-y\times3-y=11,2\)
c.\(y\times38,01-y\div100-y=1622,45\)
\(1-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):16\frac{2}{3}=0\)
tính giá trị biểu thức
\(\left(\frac{17}{10}+7-8,7\right):\left(\frac{23}{4}-\frac{11}{2}+\frac{9}{25}\right)x\left(12,98x0,25\right)+12,5\)
\(1\frac{2}{24}x5\frac{2}{5}x2x3\frac{7}{9}x2x\frac{2}{17}\)
\(2\frac{2}{17}x1\frac{1}{24}x5\frac{2}{5}x3\frac{7}{9}x2\)
\(3x\left(\frac{1}{7}+\frac{1}{3}-\frac{3}{14}\right):\frac{11}{14}\)
\(\left(1\frac{3}{2}+2\frac{1}{5}\right)x1\frac{1}{10}+\left(1\frac{7}{10}-\frac{4}{5}\right):\frac{3}{7}\)
\(A=\left(6:\frac{3}{5}-1\frac{1}{6}x\frac{6}{7}\right):\left(4\frac{1}{5}x\frac{10}{11}+5\frac{2}{11}\right)\)\(B=\left(1-\frac{1}{2}\right)x\left(1-\frac{1}{4}\right)x.......x\left(1-\frac{1}{2015}\right)x\left(1-\frac{1}{2016}\right)\)
\(C=5\frac{9}{10}:\frac{3}{2}-\left(2\frac{1}{3}x4\frac{1}{2}-2x2\frac{1}{3}\right):\frac{7}{4}\)
Tính giá trị của biểu thức sau:
\(\left(18\frac{1}{2}+5\frac{3}{8}-7\frac{5}{24}\right):16\frac{2}{3}\)
Tìm x biết:\(1-\left(3\frac{3}{8}+x-2\frac{5}{24}\right)\cdot\frac{12}{17}=0\)
Tìm x biết:
\(2-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):16\frac{2}{3}=0\)
Giup mik với mik đag gấp lắm mik like cho nha giải chi tiết nhé
BÀI 2: tìm số hữu tỹ X , biết rằng
a,\(\frac{-3}{2}-2X+\frac{3}{4}=-2\)2
b, (\(\frac{-2}{3}x-\frac{3}{5}\))(\(\frac{3}{-2}-\frac{10}{3}\))=\(\frac{2}{5}\)
c,\(\frac{x}{2}-\left(\frac{3x}{5}-\frac{13}{5}\right)=-\left(\frac{7}{5}+\frac{7}{10}.x\right)\)
d,\(\frac{2x-3}{3}+\frac{-3}{2}=\frac{5-3x}{6}-\frac{1}{3}\)
e,\(\frac{2}{3x}-\frac{3}{12}=\frac{4}{5}-\left(\frac{7}{x}-2\right)\)
Tìm X:
\(\left[\left(35\frac{5}{7}+2\frac{3}{4}\right)-5\frac{5}{7}+\frac{1}{4}\right]:\left(11+X\right)=3\)
