2.
oblicz:(rozpisz):
13 2/7 + 5 3/10 = 13 20/70 + 5 21/70 = 18 41/70
8 3/16- 3 3/4 = 8 3/16 - 3 12/16 = 7 19/16 - 3 12/16 = 4 7/16
10- 4 2/15 = 9 15/15 - 4 2/15 = 5 13/15
6 2/5 * 5/8= 32/5 * 5/8 = 4
4 2/7 : 1 2/3= 30/7 : 5/3 = 30/7 * 3/5 = 6/7 * 3/5 = 18/35
2/7 *10 *5 3/5= 2/7 * 10 * 28/5 = 2 * 2 * 4 = 4 * 4 = 16
oblicz:
12,7+ 9,47 = 22,17
200,32-32,8 = 167,52
0,17*3,8 = 0,646
0,576:1,8 = 0,32
