Привет, ребята! Давайте сократим дроби, используя наибольший общий делитель числителя и знаменателя.
1) **42/24, 35/77, 48/60, 72/96**
- 42/24 = (6*7)/(6*4) = 7/4
- 35/77 = (7*5)/(7*11) = 5/11
- 48/60 = (12*4)/(12*5) = 4/5
- 72/96 = (24*3)/(24*4) = 3/4
2) **10/100, 400/1000, 600/800, 800/1000**
- 10/100 = (10*1)/(10*10) = 1/10
- 400/1000 = (200*2)/(200*5) = 2/5
- 600/800 = (200*3)/(200*4) = 3/4
- 800/1000 = (200*4)/(200*5) = 4/5
3) **72/90, 60/105, 45/150, 84/120**
- 72/90 = (18*4)/(18*5) = 4/5
- 60/105 = (15*4)/(15*7) = 4/7
- 45/150 = (15*3)/(15*10) = 3/10
- 84/120 = (12*7)/(12*10) = 7/10
4) **56/70, 36/90, 66/110, 96/160**
- 56/70 = (14*4)/(14*5) = 4/5
- 36/90 = (18*2)/(18*5) = 2/5
- 66/110 = (11*6)/(11*10) = 6/10 = 3/5
- 96/160 = (32*3)/(32*5) = 3/5
