Дано числа: 2/3, 12/9, 25/27, 35/81, 11/18. Запишіть кожне число у вигляді дробу зі знаменником: 1) 162; 2) 1626 ; 3) 3246, де b — натуральне число. 1) 2/3 = (2 • 54b)/(3 • 54b) = 108b/162b; 12/9 = 11/9 = (11 • 18b)/(9 • 18b) = 198b/162b; 25/27 = 59/27 = (59 • 6b)/(27 • 6b) = 354b/162b; 35/81 = (35 • 2b)/(81 • 2b) = 70b/162b; 11/18 = (11 • 9b)/(18 • 9b) = 99b/162b; 2) 2/3 = (2 • 108b)/(3 • 108b) = 216b/324b; 12/9 = 11/9 = (11 • 36b)/(9 • 36b) = 396b/324b; 25/27 = 59/27 = (59 • 12b)/(27 • 12b) = 708b/324b; 35/81 = (35 • 4b)/(81 • 4b) = 140b/324b; 11/18 = (11 • 18b)/(18 • 18b) = 198b/324b; 3) 2/3 = (2 • 216b)/(3 • 216b) = 432b/648b; 12/9 = 11/9 = (11 • 72b)/(9 • 72b) = 792b/648b; 25/27 = 59/27 = (59 • 24b)/(27 • 24b) = 1416b/648b; 35/81 = (35 • 8b)/(81 • 8b) = 280b/648b; 11/18 = (11 • 36b)/(18 • 36b) = 396b/648b.
