Question

x chia 1/2 cộng 3/4 =9/8

Answer 1

\(x\div\frac{1}{2}+\frac{3}{4}=\frac{9}{8}\)

\(\Rightarrow x\div\frac{1}{2}=\frac{9}{8}-\frac{6}{8}\)

\(\Rightarrow x\div\frac{1}{2}=\frac{3}{8}\)

\(\Rightarrow x=\frac{3}{8}\times\frac{1}{2}\)

\(\Rightarrow x=\frac{3}{16}\)

Answer 2

\(x:\frac{1}{2}+\frac{3}{4}=\frac{9}{8}\)

\(\Leftrightarrow x:\frac{1}{2}=\frac{9}{8}-\frac{3}{4}\)

\(\Leftrightarrow x:\frac{1}{2}=\frac{3}{8}\)

\(\Leftrightarrow x=\frac{3}{8}.\frac{1}{2}\)

\(\Rightarrow x=\frac{3}{16}\)

vậy...

Answer 3
