DAU COROANĂ

Answer 1

$\frac{80}{20} = \frac{80 : 20}{20 : 20} = 4 \\ \\ \frac{150}{60} = \frac{150 : 30}{60 : 30} = \frac{5}{2} \\ \\ \frac{25}{35} = \frac{25 : 5}{35 : 5} = \frac{5}{7} \\ \\ \frac{18}{24} = \frac{18 : 6}{24 : 6} = \frac{3}{4} \\ \\ \frac{15}{21} = \frac{15 : 3}{21 : 3} = \frac{5}{7} \\ \\ \frac{300}{600} = \frac{300 : 300}{600 : 300} = \frac{1}{2} \\ \\ \frac{33}{99} = \frac{33 : 33}{99 : 33} = \frac{1}{3} \\ \\ \frac{333}{999} = \frac{333 : 333}{999 : 333} = \frac{1}{3}$

Answer 2

80 / 20 = ( 80 : 20 ) / ( 20 : 20 ) = 4 / 1 = 4

150 / 60 = ( 150 : 10 ) / ( 60 : 10 ) = 15 / 6 = ( 15 : 3 ) / ( 6 : 3 ) = 5 / 2

25 / 35 = ( 25 : 5 ) / ( 35 : 5 ) = 5 / 7

18 / 24 = ( 18 : 6 ) / ( 24 : 6 ) = 3 / 4

15 / 21 = ( 15 : 3 ) / ( 21 : 3 ) = 5 / 7

300 / 600 = ( 300 : 100 ) / ( 600 : 100 ) = 3 / 6 = ( 3 : 3 ) / ( 6 : 3 ) = 1 / 2

33 / 99 = ( 33 : 33 ) / ( 99 : 33 ) = 1 / 3

333 / 999 = ( 333 : 333 ) / ( 999 : 333 ) = 1 / 3
