\(\left(\frac{1}{4}xX-\frac{1}{8}\right)x\frac{3}{4}=\frac{1}{4}\)
\(\left(\frac{1}{4}xX-\frac{1}{8}\right)=\frac{1}{4}:\frac{3}{4}\)
\(\left(\frac{1}{4}xX-\frac{1}{8}\right)=\frac{1}{3}\)
\(\frac{1}{4}xX=\frac{1}{3}+\frac{1}{8}\)
\(\frac{1}{4}xX=\frac{11}{24}\)
\(x=\frac{11}{24}:\frac{1}{4}\)
\(x=\frac{11}{6}\)
1/4 . x -1/8 = 3/4 : 1/4
1/4 . x -1/8 = 3
1/4 . x =3+1/8
1/4 . x = 25/8
x = 25/8 : 1/4
x = 25/2
Lớp 7 rồi nên mk viết dấu nhân là ( . )nhé
Mk chép nhầm đầu bài, xin lỗi nhé
1/4 . x -1/8=1/4 : 3/4
1/4 . x -1/8= 1/3
1/4 . x =1/3+1/8
1/4 . x = 11/24
x = 11/24 : 1/4
x = 11/6
\(\left(\frac{1}{4}.x-\frac{1}{8}\right).\frac{3}{4}=\frac{1}{4}\)
\(\frac{1}{4}x-\frac{1}{8}=\frac{1}{4}:\frac{3}{4}\)
\(\frac{1}{4}x-\frac{1}{8}=\frac{1}{3}\)
\(\frac{1}{4}x=\frac{1}{3}+\frac{1}{8}\)
\(\frac{1}{4}x=\frac{11}{24}\)
\(x=\frac{11}{6}\)
