[tex] \frac{45}{15} = \frac{3 \times 3 \times 5}{5 \times 3} = 3[/tex]
[tex] \frac{9}{27} = \frac{3 \times 3}{3 \times 3 \times 3} = \frac{1}{3} [/tex]
[tex] \frac{18}{36} = \frac{3 \times 3 \times 2}{3 \times 3 \times 2 \times 2} = \frac{1}{2} [/tex]
[tex] \frac{15}{45} = \frac{5 \times 3}{3 \times 3 \times 5} = \frac{1}{3} [/tex]
[tex] \frac{90}{100} = \frac{5 \times 2 \times 3 \times 3}{5 \times 2 \times 5 \times 2} = \frac{9}{10} [/tex]
[tex] \frac{110}{66} = \frac{11 \times 5 \times 2}{11 \times 3 \times 2} = \frac{5}{3} [/tex]
