Приведите дроби 3/4,1/2,3/5,3/10,9/20,2/25,9/50 к знаменателю 100

Приведем дроби 3/4, 1/2, 3/5, 3/10, 9/20, 2/25, 9/50 к знаменателю 100.1) 3/4 = (3 * 25)/(4 * 25) = 75/100;2) 1/2 = (1 * 50)/(2 * 50) = 50/100;3) 3/5 = (3 * 20)/(5 * 20) = 60/100;4) 3/10 = (3 * 10)/(10 * 10) = 30/100;5) 9/20 = (9 * 5)/(20 * 5) = 45/100;6) 2/25 = (2 * 4)/(25 * 4) = 8/100;7) 9/50 = (9 * 2)/(50 * 2) = 18/100.
