1) 5/6 : 4/7 = 5/6 * 7/4 = (5 * 7)/(6 * 4) = 35/24;
Ответ: 35/24.
2) 6/35 : 48/49 = 6/35 * 49/48 = (6 * 49)/(35 * 48) = (6 * 7 * 7)/(7 * 5 * 6 * 8) = 7/(5 * 8) = 7/40;
Ответ: 7/40.
3) 8/15 : 32/75 = 8/15 * 75/32 = (8 * 75)/(15 * 32) = (8 * 15 * 5)/(15 * 8 * 4) = 5/4;
Ответ: 5/4.
4) 45/56 : 54/49 = 45/56 * 49/54 = (45 * 49)/(56 * 54) = (9 * 5 * 7 * 7)/(7 * 8 * 6 * 9) = (5 * 7)/(8 * 6) = 35/48;
