Question

Fill in the missing fractions: $\frac{7}{10}-\boxed{}=\frac{3}{10}$

Answer 1

Find the missing fraction:

Given, $\frac{7}{10}-\boxed{}=\frac{3}{10}$

Let the missing fraction be $x$, then,

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

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

$=\frac{4}{10}$

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

Hence, $\frac{\mathbf{7}}{\mathbf{10}}\mathbf{-}\boxed{\frac{\mathbf{2}}{\mathbf{5}}}\mathbf{=}\frac{\mathbf{3}}{\mathbf{10}}$
