Question

5-(4 nhân x +1/4 ) :1/4=4

ai nhanh mk tk

Answer 1

5-(4xX+1/4):1/4=4
5-4xX+1/4:1/4=4
5-4xX=4
4xX=1
X=1/4
 

Answer 2

ds là 15/16

Answer 3

\(5-\left(4x+\frac{1}{4}\right):\frac{1}{4}=4\)

\(\Rightarrow\left(4x+\frac{1}{4}\right):\frac{1}{4}=5-4=1\)

\(\Rightarrow4x+\frac{1}{4}=\frac{1}{4}\)

\(\Rightarrow4x=\frac{1}{4}-\frac{1}{4}=0\)

\(\Rightarrow x=0:4=0\)

Answer 4

\(5-\left(4xX+\frac{1}{4}\right):\frac{1}{4}=4\)

\(\left(4xX+\frac{1}{4}\right):\frac{1}{4}=5-4\)

\(\left(4xX+\frac{1}{4}\right):\frac{1}{4}=1\)

\(\left(4xX+\frac{1}{4}\right)=1x4\)

\(\left(4xX+\frac{1}{4}\right)=4\)

\(4xX=4-\frac{1}{4}\)

\(4xX=\frac{16}{4}-\frac{1}{4}\)

\(4xX=\frac{15}{4}\)

      \(X=\frac{15}{4}:4\)

       \(X=\frac{15}{16}\)
