Answer 1

Odpowiedź:

a)

4 * 2/5 = 8/5 = 1 3/5

10 * 5/8 = 5 * 5/4 = 25/4 = 6 1/4

7/15 * 10 = 7/3 * 2 = 14/3 = 4 2/3

100 * 2/50 = 2 * 2 = 4

45 * 11/18 = 5 * 11/2 = 55/2 = 27 1/2

64 * 9/16 = 4 * 9 = 36

b)

9/15 * 5/6 = 3/3 * 1/2 = 3/6 = 1/3

5/12 * 4/30 = 1/3 * 1/6 = 1/18

13/28 * 7/39 = 1/4 * 1/3 = 1/12

2/3 * 111/222 = 1/3 * 1/2 = 1/6

81/100 * 4/27 = 3/25 * 1 = 3/25

24/50 * 5/27 = 8/10 * 1/9 = 8/90 = 4/45
