Question

3/8 x X+1/4xX=2/5

Answer 1

\(\frac{3}{8}\times x+\frac{1}{4}\times x=\frac{2}{5}\)

\(\Rightarrow x\times\left(\frac{3}{8}+\frac{1}{4}\right)=\frac{2}{5}\)

\(\Rightarrow x\times\frac{5}{8}=\frac{2}{5}\)

\(\Rightarrow x=\frac{16}{25}\)

bn ơi / là j bn

Answer 3

\(\frac{3}{8}\times x+\frac{1}{4}\times x=\frac{2}{5}\)

\(\left(\frac{3}{8}+\frac{1}{4}\right)\times x=\frac{2}{5}\)

Đến đây tự làm :v

Answer 4

=>(3/8+1/4)x=2/5                   nhớ k nhé mọi người

=>5/8x=2/5

Answer 5

3/8xX+1/4xX=2/5

(3/8+1/4)xX=2/5

5/8xX=2/5

       X=2/5:5/8

       X=16/25

Answer 6

Cảm ơn mọi ng nha

Answer 7

\(\frac{3}{8}\times x+\frac{1}{4}\times x=\frac{2}{5}\)

\(\left(\frac{3}{8}+\frac{1}{4}\right)\times x=\frac{2}{5}\)

\(\left(\frac{3}{8}+\frac{2}{8}\right)\times x=\frac{2}{5}\)

\(\frac{5}{8}\times x=\frac{2}{5}\)

            \(x=\frac{2}{5}:\frac{5}{8}\)

           \(x=\frac{16}{25}\)

Vậy \(x=\frac{16}{25}\)

Chúc bạn học tốt !!!
