Question

1/2.x + 1/8 . x= 3/4

Answer 1

Ta có: \(\frac{1}{2}x+\frac{1}{8}x=\frac{3}{4}\)

\(\Leftrightarrow x\cdot\frac{5}{8}=\frac{3}{4}\)

hay \(x=\frac{3}{4}:\frac{5}{8}=\frac{3}{4}\cdot\frac{8}{5}=\frac{24}{20}=\frac{6}{5}\)

Vậy: \(x=\frac{6}{5}\)

Answer 2

x=6/5

Answer 3

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

\(\Leftrightarrow\frac{x}{2}+\frac{x}{8}=\frac{3}{4}\)

\(\Leftrightarrow4x+x=6\)

\(\Leftrightarrow5x=6\)

\(\Leftrightarrow x=\frac{6}{5}\)

Answer 4

=> x.(1/2 + 1/8)=3/4

= >x. 5/8 = 3/4

= > x = 3/4 : 5/8

=> x = 3/4 . 8/5

=> x = 24/20 = 6/5
