Question

5/4-1/4 *x:1/2+1/2=1/4

Answer 1

\(\frac{5}{4}-\frac{1}{4}.x:\frac{1}{2}+\frac{1}{2}=\frac{1}{4}\)

\(\frac{1}{4}.x:\frac{1}{2}=\frac{5}{4}-\frac{1}{4}-\frac{1}{2}\)

\(\frac{1}{4}.x:\frac{1}{2}=\frac{1}{2}\)

\(\frac{1}{4}.x=\frac{1}{2}.\frac{1}{2}=\frac{1}{4}\)

\(=>x=\frac{1}{4}:\frac{1}{4}=1\)

Answer 2

Xin lỗi cậu, mình tính lộn

\(\frac{5}{4}-\frac{1}{4}.x:\frac{1}{2}+\frac{1}{2}=\frac{1}{4}\)

\(\frac{5}{4}-\frac{1}{4}.x:\frac{1}{2}=-\frac{1}{4}\)

\(\frac{1}{4}.x:\frac{1}{2}=\frac{5}{4}+\frac{1}{4}=\frac{3}{2}\)

\(\frac{1}{4}.x=\frac{3}{2}.\frac{1}{2}=\frac{3}{4}\)

\(x=\frac{3}{4}:\frac{1}{4}=\frac{3}{4}.4\)

\(x=3\)
