Odpowiedź:
a)
16/23 * 69/88 = 2 * 3/11 = 6/11
b)
0,64 * 1 3/32 = 0,64 * 1,09375 = 1,06
c)
7/13 * 2 9/28 = 7/13 * 65/28 = 5/4 = 1 1/4
d)
9 1/3 * 2,4 * 3 3/14 = 28/3 * 24/10 * 45/14 = 14 * 8/5 * 45/14 = 8 * 9 = 72
e)
1/28 * 1 3/32 * 1,92 = 1/28 * 35/32 * 192/100 = 1/4 * 5/32 * 48/25 = 1/32 * 12/5 = 2/8 * 3/5 = 6/40 = 2/20
f)
1215 * 2 11/1215 = 1215 * 2441/1215 = 2441
