Question
Replace $\Box$ by the correct number:$\Box-\frac{5}{8}=\frac{1}{4}$

Answer

$\frac{7}{8}-\frac{5}{8}=\frac{1}{4}$Solution:
Given: $\Box-\frac{5}{8}=\frac{1}{4}$
$\Rightarrow\Box=\frac{5}{8}+\frac{1}{4}$
$\Rightarrow\Box=\frac{5\times1}{8\times1}+\frac{1\times2}{4\times2}$ (because LCM of 8 and 4 is 8)
$\Rightarrow\Box=\frac{5}{8}+\frac{2}{8}$
$\Rightarrow\Box=\frac{5+2}{8}$
$\Box=\frac{7}{8}$
