Przykłady ułamków: ułamki właściwe ( < 1) 1/2; 1/4 ; 3/10; 2/5; 7/10; 1/20; 3/100 ; 23 /100 , itp. ułamki niewłaściwe ( ≥ 1 ) 3/2; 5/4; 12/10; 25/10; 100/100; 120/100, itp. Ułamek 1/100 = 0,01 = 1 % ( jeden procent ) zatem: 1/2 = 50/100 = 0,50 = 50% 1/4 = 25/100 = 0,25 = 25% 3/10 = 30/100 = 0,30 = 30% 2/5 = 40/100 = 0,40 = 40 % 7/10 = 70/100 = 0,70 = 70 % 1/20 = 5/100 = 0,05 = 5 % 3/100 = 0,03 = 3 % 23/100 = 0,23 = 23 % oraz 3/2 = 150/100 = 1,50 = 150 % 5/4 = 125/100 = 1,25 = 125 % 12/10 = 120/100 = 1,20 = 1,2 = 120% 25/10 = 250/100 = 2,50 = 2,5 = 250 % 100/100 = 1,0 = 1 = 100 % 120/100 = 1,20 = 1,2 = 120 % , itp. ========================= 73% = 73/100 = 0,37 19% = 19/100 = 0,19 132% = 132/100 =1,32 270% = 270/100 = 2,70 = 2,7 400% = 400/100 = 4,00 = 4 7% = 7/100 = 0,07 102 % = 102/100 =1,02 itp.
Witam! Ogólnie sprawa wygląda tak: 1% to 1/100. Tak więc: 1% = 1/100; 2% = 2/100 = 1/50; 4% = 4/100 = 1/25; 5% = 5/100 = 1/20; 10% = 10/100 = 1/10; 20% = 20/100 = 1/5; 50% = 50/100 = 1/2; 75% = 75/100 = 3/4 90% = 90/100 = 9/10; 100% = 100/100 = 1;
