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 $\frac{7}{27}$.
