Question

Find in the missing fractions :
$\left(i\right)\frac{7}{10}-\square =\frac{3}{10}$
$\left(ii\right)\square +\frac{5}{27}=\frac{12}{27}$
$\left(iii\right)\square -\frac{5}{7}=\frac{2}{7}$.

Answer 1

$\left(i\right)\frac{7}{10}-\square =\frac{3}{10}$

Let the missing fraction be $x$.

$\Rightarrow \frac{7}{10}-x=\frac{3}{10}$

$\Rightarrow -x=\frac{3}{10}-\frac{7}{10}$

$\Rightarrow -x=\frac{-4}{10}$

$\Rightarrow x=\frac{4}{10}$

$\left(ii\right)\square +\frac{5}{27}=\frac{12}{27}$

Let the missing fraction be $x$

$\Rightarrow x+\frac{5}{27}=\frac{12}{27}$

$\Rightarrow x=\frac{12}{27}-\frac{5}{27}$

$\Rightarrow x=\frac{7}{27}$

$\left(iii\right)\square -\frac{5}{7}=\frac{2}{7}$

Let the missing fraction be $x$

$\Rightarrow x-\frac{5}{7}=\frac{2}{7}$

$\Rightarrow x=\frac{2}{7}+\frac{5}{7}$

$\Rightarrow x=\frac{7}{7}=1$
