Answer 2

a)1\4 2\3

$\frac{1}{4}\frac{2}{3}=\frac{1}{6}\quad \left(\mathrm{Decimal:\quad }\:0.16666\dots \right)\\\\\frac{1}{4}\cdot \frac{2}{3}\\\\\frac{1}{2\cdot \:2}\cdot \frac{2}{3}\\\\\\\frac{1}{2}\cdot \frac{1}{3}=\frac{1\cdot \:1}{2\cdot \:3}\\\\\\\\\frac{1}{2\cdot \:3}\\\\\\\\\frac{1}{6}$

b)4\5 6\8

$\frac{4}{5}\frac{6}{8}=\frac{3}{5}\quad \left(\mathrm{Decimal:\quad }\:0.6\right)\\\\\frac{4}{5}\cdot \frac{6}{8}\\\\\frac{6}{8}=\frac{3}{4}\\\\\frac{4}{5}\cdot \frac{3}{4}\\\\\\\frac{3}{5}$

c)1\5 4\6

$\frac{1}{5}\frac{4}{6}=\frac{2}{15}\quad \left(\mathrm{Decimal:\quad }\:0.13333\dots \right)\\\\\\\frac{1}{5}\cdot \frac{4}{6}\\\\\frac{4}{6}=\frac{2}{3}\\\frac{1}{5}\cdot \frac{2}{3}=\frac{1\cdot \:2}{5\cdot \:3}\\\frac{2}{5\cdot \:3}\\\\\frac{2}{15}\\\\\frac{1}{5}\cdot \frac{2}{3}=\frac{1\cdot \:2}{5\cdot \:3}\\\\\\frac{2}{5\cdot \:3}\\\\\frac{2}{15}$

d)3/4 > 5/10

e) 3/10 > 1/6
