$\dfrac{1}{4}$ + $\dfrac{1}{12}$ = $\dfrac{x}{3}$
Có : $\dfrac{1}{4}$ + $\dfrac{1}{12}$
= $\dfrac{3}{12}$ + $\dfrac{1}{12}$
= $\dfrac{4}{12}$
= $\dfrac{1}{3}$
=> x = 1
Vậy x = 1
\frac{1}{4} + \frac{1}{12} = \frac{x}{3}
\frac{1× 3}{4×3} + \frac{1}{12} = \frac{x}{3}
\frac{3}{12} + \frac{1}{12} = \frac{x}{3}
\frac{3+ 1}{12} = \frac{x}{3}
\frac{4}{12} = \frac{x}{3}
\frac{4: 4}{12 : 4} = \frac{x}{3}
\frac{1}{3} = \frac{x}{3}
⇒ x = 1
Chúc bạn học tốt~
