Математика: Сократите дробь: 2*3/2*5; 5*7/3*5; 3*7/6*5; 9*5/7*3; 8*3/6*24; 5*27/18*15.

Ivan733822 · Answer

(2*3)/(2*5)  = (1*3)/(1*5) = 3/5(5*7)/(3*5) = (1*7)/(3*1) = 7/3  = 2   1/3(3*7)/(6*5) = (1*7)/(2*5) = 7/10(9*5)/(7*3) = (3*5)/(7*1) = 15/7  = 2   1/7(8*3)/(6*24) = (1*1)/(2*3) = 1/6(5*27)/(18*15) = (1*3)/(2*3) = (1*1)/(2*1)= 1/2...
