Question

x/2=z/3=a/4=5

Answer 1

\(\left\{{}\begin{matrix}\frac{x}{2}=5\\\frac{z}{3}=5\\\frac{a}{4}=5\end{matrix}\right.=>\left\{{}\begin{matrix}\frac{x}{2}=\frac{10}{2}\\\frac{z}{3}=\frac{15}{3}\\\frac{a}{4}=\frac{20}{4}\end{matrix}\right.=>\left\{{}\begin{matrix}x=10\\z=15\\a=20\end{matrix}\right.\)(T/M)

Vậy......

Answer 2

x/2=z/3=a/4=5

sử dụng tính chất bắc cầu ta có

x/2=5=> x=2×5 => x=10

z/3=5 => z=3×5 => z=15

a/4=5 => a=4×5 =>a=20

Vậy x=10 , z=15 , a=20
