[tex]a) \frac{20}{30} = \\ \frac{20 \div 10}{30 \ \div 10} = \\ \blue{ \frac{2}{3}} [/tex]
[tex]b) \frac{250}{350} = \\ \frac{250 \div 50}{350 \div 50} = \\ \purple{ \frac{5}{7} } [/tex]
[tex]c) \frac{2 \times 3 \times 7}{3 \times 7 \times 11} = \\ \frac{2(3 \times 7) \div (3 \times 7)}{11(3 \times 7) \div ( 3 \times 7)} = \\ \green{ \frac{2}{11} } [/tex]
[tex] \frac{ {2}^{3} }{ {2}^{5} } = \\ \frac{8 \div 8}{32 \div 8} = \\ \orange{ \frac{1}{4} }[/tex]
