Question

Fill in the missing fraction:

$\square +\frac{5}{27}=\frac{12}{27}$

Answer 1

Let the missing number be $x$

Consider

$$\begin{gathered} \Rightarrow x+\frac{2}{27}=\frac{12}{27} \\ \Rightarrow x=\frac{12}{27}-\frac{5}{27} \\ \Rightarrow x=\frac{12-5}{27} \\ \Rightarrow x=\frac{7}{27} \end{gathered}$$

Hence, the required fraction is $\frac{7}{27}$
