a)
[tex]2 \times (\frac{1}{5}) \div 1 \times ( \frac{1}{5} )[/tex]
[tex] \frac{2}{10} \div \frac{1}{5} [/tex]
[tex] \frac{2}{10} \times \frac{5}{1} = 1 \: \: answer[/tex]
b)
[tex] \frac{1}{4} \times 248 = 62 \: \: answer[/tex]
c)
[tex]3 ( \frac{1}{2} ) + 4( \frac{3}{4} ) = \frac{3}{6 } + \frac{12}{16} \: \: \: \: \: \: \: \: \: \: (lcm = 48)[/tex]
[tex] \frac{24}{48} + \frac{36}{48} = \frac{60}{48} [/tex]
