Answer 1

2 3/4 - 1 2/3 = 2 9/12 - 1 8/12 = 1 1/12
4 1/3 - 5/6= 4 2/6 - 5/6 = 3 1/2
8 3/4 - 2 1/8= 8 6/8 - 2 1/8 = 6 5/8
4 4/5 - 1 1/7= 4 28/35 - 1 5/35 = 3 23/35
8 1/2 - 6 5/7= 8 7/14 - 6 10/14 = 1 11/14
5/6 * 3/7 * 4/5 = 60/168 = 15/42
4/5 * 2 6/7 * 1 3/4= 4/5 * 20/7 * 7/4 = 560/140 = 4
4* 3 1/8*3/10= 4 * 25/8 * 3/10 = 300/800 = 3/8
5/14 * 7/10 = 35/140 = 4
2*2*1/4 = 4 * 1/4 = 1

Answer 2

2 3/4 - 1 2/3 = 2 9/12 - 1 8/12 = 1 1/12
4 1/3 - 5/6 = 3 4/3 - 5/6 =3 8/6 - 5/6 = 3 3/6 = 3 1/2
8 3/4 - 2 1/8 = 8 6/8 - 2 1/8 = 6 5/8
4 4/5 - 1 1/7 = 4 28/35 - 1 5/35 = 3 23/35
8 1/2 - 6 5/7 = 8 7/14 - 6 10/14 = 7 21/10 - 1 11/14 = 6 11/14
5/6 * 3/7 * 4/5 = 60/210 = 2/7
4/5 * 2 6/7 * 1 3/4 = 4/5 * 20/7 * 7/4 = 560/140 = 4
4* 3 1/8*3/10 = 4 * 25/8 * 3/10 = 300/80 = 3 3/4
5/14 * 7/10 = 35/140 = 1/4
2*2*1/4=1

bardziej szczegółowo sie chyba nie da
