# Fill in the missing fractions.(a) $\frac{7}{10}-\square=\frac{3}{10}$(b) $\square-\frac{3}{21}=\frac{5}{21}$(c) $\square-\frac{3}{6}=\frac{3}{6}$(d) $\square+\frac{5}{27}=\frac{12}{27}$

To do :

We have to find the missing fractions.

Solution :

(a) Let the missing fraction be $x$

This implies,

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

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

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

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

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

Therefore, the missing fraction is $\frac{2}{5}$.

(b) Let the missing fraction be $x$

This implies,

$x-\frac{3}{21}=\frac{5}{21}$

$x=\frac{5}{21}+\frac{3}{21}$

$x=\frac{5+3}{21}$

$x=\frac{8}{21}$

Therefore, the missing fraction is $\frac{8}{21}$.

(c) Let the missing fraction be $x$

This implies,

$x-\frac{3}{6}=\frac{3}{6}$

$x=\frac{3}{6}+\frac{3}{6}$

$x=\frac{3+3}{6}$

$x=\frac{6}{6}$

$=1$

Therefore, the missing fraction is $1$.

(d) Let the missing fraction be $x$

This implies,

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

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

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

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

Therefore, the missing fraction is $\frac{7}{27}$.
