\(x-\frac{1}{2}=\frac{2}{4}+\frac{1}{2}\)
\(x-\frac{1}{2}=1\)
\(x=1+\frac{1}{2}\)
\(x=\frac{3}{2}\)
\(x-\frac{1}{2}=\frac{2}{4}+\frac{1}{2}\)
\(x-\frac{1}{2}=1\)
\(x=1+\frac{1}{2}\)
\(x=\frac{3}{2}\)
tìm x:
\(x.\frac{1}{2}=\frac{1}{2}+\frac{2}{4}\)
tìm x:
\(x+\frac{3}{4}=\frac{1}{2}.\frac{2}{3}\)
tìm x biết:
\(\left(x+\frac{1}{2}\right)+\left(x+\frac{1}{4}\right)+\left(x+\frac{1}{8}\right)+\left(x+\frac{1}{16}\right)=\frac{23}{16}\)
*Tìm x:
a,\(X+\frac{1}{2}-\frac{3}{4}=\frac{5}{6}\) b,\(Xx\frac{1}{3}:\frac{2}{5}=\frac{4}{3}\)
Tìm x:\(\left(x+\frac{1}{2}\right)+\left(x+\frac{1}{4}\right)+\left(x+\frac{1}{8}\right)+\left(x+\frac{1}{16}\right)=\frac{23}{16}\)
Trả lời:x là......
Tìm X
\(\frac{1}{4}x\frac{1}{5}xX=\frac{1}{2}\)
Tìm x, biết:
x+\(\frac{1}{2}\)=\(\frac{1}{4}\)+\(\frac{2}{4}\)
tìm x:
\(x-\frac{1}{2}=\frac{2}{4}\)
1) Tính A biết rằng :
A = \(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}+......+\frac{1}{64}\)
2) So sánh 2 phép tính sau:
\(\frac{1+2+3+4+5+6+7}{2+3+4+5+6+7+8}\)và \(\frac{1}{2}+\frac{2}{3}+\frac{3}{4}+\frac{6}{5}+\frac{7}{6}+\frac{8}{7}\)
3) Tìm \(x\)biết:
\(\frac{x\times7}{x}=7\) \(\frac{x}{x\times6}=\frac{1}{6}\)
4) Tìm 1 phân số nếu lấy \(\frac{12}{5}\)trừ đi phân số đó rồi chia cho \(\frac{5}{7}\)thì được \(\frac{12}{5}\).
