Question

Fill in the missing fractions:

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

Answer 1

Let the missing fraction is $\mathrm{x}$.

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

By transpose methode

take $\mathrm{x}$ on the right-hand side and bring $\frac{3}{10}$ on the left hand side

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

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

we can interchange the positions

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

Hence the missing fraction is $\frac{4}{10}$.
