Answer 2

Răspuns:

Bună,

$a)75 \% = \\ \frac{75}{100} = \\ \frac{75 \div 25}{100 \div 25} = \\ \purple{ \frac{3}{4} }$

$b) 15 \% \\ \frac{15}{100} = \\ \frac{15 \div 5}{100 \div 15} = \\ \green{ \frac{3}{20} }$

$c)28 \% = \\ \frac{28}{100} = \\ \frac{28 \div 4}{100 \div 4} = \\ \blue{\frac{7}{25} }$

$d) 120\% = \\ \frac{120}{100} = \\ \frac{120 \div 20}{100 \div 20} = \\ \red{ \frac{6}{5} }$

$e)36 \% = \\ \frac{36}{100} = \\ \frac{36 \div 4}{100 \div 4} = \\ \orange{ \frac{9}{25} }$

$f)125 \% = \\ \frac{125}{100} = \\ \frac{120 \div 25}{100 \div 25} = \\ \pink{ \frac{5}{4} }$
