[tex]3 \div \frac{5}{2} = \frac{1}{3} \div \frac{5}{2} = \frac{1}{3} \times \frac{2}{5} = \frac{2}{15} [/tex]
b)
[tex]5 \div \frac{3}{4} = \frac{1}{5} \div \frac{3}{4} = \frac{1}{5} \times \frac{4}{3} = \frac{4}{15} [/tex]
c)
[tex]2 \div 3 \frac{1}{2} = \frac{1}{2} \div \frac{7}{2} = \frac{1}{2} \times \frac{ {2}^{2} }{7} = \frac{1}{1} \times \frac{1}{7} = \frac{1}{7} [/tex]
d)
[tex]8 \div \frac{1}{2} = \frac{1}{8} \div \frac{1}{2} = \frac{1}{8} \times \frac{ {2}^{2} }{1} = \frac{1}{4} \times \frac{1}{1} = \frac{1}{4} [/tex]
