Question

a)
$\frac{1}{4} + \frac{1}{6}$
b)
$\frac{1}{3} - \frac{1}{9}$
c)
$\frac{1}{3} - \frac{1}{6}$
d)
$\frac{1}{3} + \frac{1}{9} + \frac{1}{4} + \frac{1}{6}$

​

Answer 1

a) $\frac{1}{4}+\frac{1}{6}=\frac{3}{12}+\frac{2}{12}=\frac{5}{12}$

b) $\frac{1}{3}-\frac{1}{9}=\frac{3}{9}-\frac{1}{9}=\frac{2}{9}$

c) $\frac{1}{3}-\frac{1}{6}=\frac{2}{6}-\frac{1}{6}=\frac{1}{6}$

d) $\frac{1}{3}+\frac{1}{9}+\frac{1}{4}+\frac{1}{6}=\frac{12}{36}+\frac{4}{36}+\frac{9}{36}+\frac{6}{36}=\frac{31}{36}$
