Answer 2

Odpowiedź:
a) 3 x 7/8 = 3/1 x 7/8 = 21/8 =

2 i 5/8

b) 8/7 x 3 = 8/7 x 3/1 = 24/7 =
3 i 3/7

c) 2 x 1 i 1/7 = 2/1 x 8/7 = 16/7

2 i 2/7

d) 2 i 1/5 x 3 = 11/5 x 3/1 = 33/5 = 6 i 3/5

e) 5 x 10 i 1/2 = 5/1 x 21/2 = 105/2 = 52 i 1/2

f) 10 x 8 i 2/3 = 10/1 x 26/3 =

260/3 = 86 i 2/3

g) 5 x 7/10 = 5/1 x 7/10 = 35/10 = 3 i 5/10 = 3 i 1/2

h) 2/7 x 14 = 2/7 x 14/1 = 28/7 = 4

i) 2/8 x 12 = 2/8 x 12/1 = 24/8

= 3

j) 4 x 5 i 5/12 = 4/1 x 65/12 (skracamy 4 i 12 czyli to będzie 1 i 3) 1/1 x 65/3 = 65/3

= 21 i 2/3

k) 6 i 2/8 x 6 = 50/8 x 6/1 = 300/8 = 37 i 4/8 = 37 i 1/2

l) 3 x 5 i 5/6 = 3/1 x 35/6 = 105/6 = 17 i 3/6 = 17 i 1/2
