Question

simplifique as frações abaixo até torna las irredutiveis 90/100 80 /20 20/100 8/24

Answer 1

$\frac{90}{100} =\frac{10*9}{10*10} =\frac{9}{10} \\\\\frac{80}{20}=\frac{20*4}{20*1} =\frac{4}{1} =4\\\\\frac{20}{100} =\frac{20*1}{20*5}=\frac{1}{5} \\\\\frac{8}{24} =\frac{8*1}{8*3} =\frac{1}{3}$

Answer 2

$\frac{ {90}^{ \div 10} }{ {100}^{ \div 10} } = \bf{ \frac{9}{10} }$

$\frac{80}{20} = \bf{4}$

$\frac{ {20}^{ \div 20} }{ {100}^{ \div 20} } = \bf{ \frac{1}{5} }$

$\frac{ {8}^{ \div 8} }{ {24}^{ \div 8} } = \bf{ \frac{1}{3} }$
