Answer 1

% = 4/5 //*100 100% = 80 25% = 0.125 //|*4 100% = 0,5 66% = 16.83 //:66 1% = 0,255 //*100 100% = 25,5 97% = 228,435 //:97 1% = 2,355 //*100 100% = 235.5 33 i 1/3 = 14/27 100/3 = 14/27 //:100 1/3 = 7/1350 //*3 1 = 7/450 4,5 % = 25,2 //:4.5 1% = 5.6 //*100 100% = 560 125% = 34,375 //:125 1% = 0,275 //*100 100% = 27,5 200% = 2 //:2 100% = 1

Answer 2

1% to 4/5
100 * 4/5 = 80

25% to 0,125
25% = 1/4
4 * 0,125 = 1/2 = 0,5

66% to 16,83
66 % - 16,83
100% - x
x = 100% * 16,83 /66% = 1683/66 = 51/2 = 25 1/2

97% to 228,435
97% - 228,435
100% - x
x = 100% * 228,435 /97% = 22843,5 /97 = 235 1/2

125% to 34,375
125% - 34,375
100% - x
x = 100% * 34,375 / 125% = 3437,5 /125 = 27 1/2

200% to 2
no to tu wiadomo 200% : 2 = 100 % czyli 1
