a) \(\frac{3}{8}\) + \(\frac{1}{{16}}\)

= \(\frac{6}{{16}}\) + \(\frac{1}{{16}}\)

= \(\frac{7}{{16}}\)

b) \(\frac{1}{5}\) + \(\frac{3}{{10}}\)

= \(\frac{2}{{10}}\) + \(\frac{3}{{10}}\)

= \(\frac{5}{{10}} = \frac{1}{2}\)

c) \(\frac{2}{3}\) + \(\frac{4}{3}\)

= \(\frac{6}{3}\)

= 2

d) \(\frac{3}{4}\) + \(\frac{2}{5}\)

= \(\frac{{15}}{{20}}\) + \(\frac{8}{{20}}\)

= \(\frac{{23}}{{20}}\)
