Question

what number should we added to (1/4+1/3) to get 2/3​

Answer 1

Answer:

Step-by-step explanation:

let the no be x

\begin{gathered}\frac{1}{4} + \frac{1}{3} + x = \frac{2}{3 } \\ \frac{3 + 4 + 12x }{12} = \frac{2}{3} \\ \frac{7 + 12x}{12} = \frac{2}{3} \\ 21 + 36x = 24 \\ 36x = 24 - 21 \\ x = \frac{3}{36} \\ x = \frac{1}{12}\end{gathered}
