Zad. 2 i 5 !! Pomóżcie mi ! wiem ze to łatwe ale ja nie mam czasu tego zrobic !

Answer 1

Zad. 2

3/5 + 7/10 = 6/10 + 7/10 = 13/10 = 1 i 3/10
4/15 - 4/15 = 0
11/30 + 1/6 = 11/30 + 5/30 = 15/30 = 1/2 
2 i 9/16 - 1 i 1/4 = 2 i 9/16 - 1 i 4/16  = 1 i 5/16
12 i 2/3 + 1 i 3/4 = 12 i 8/12 + 1 i 9/12 = 13 i 17/12 = 14 i 5/12
8 i 1/8 - 2/3 = 8 i 3/24 - 16/24 = 7 i 27/24 - 16/24 = 7 i 9/24
6 i 1/4 - 3 i 5/6 = 6 i 6/24 - 3 i 20/24 = 5 i 30/24 - 3 i 20/24 = 2 i 10/24 = 2 i 5/12
6 i 1/3 - 3 i 5/6 = 6 i 2/6 - 3 i 5/6 = 5 i 8/6 - 3 i 5/6 = 2 i 3/6 = 2 i 1/3

Answer 2

Zad2 
a) 3/5 + 7/10 = 6/10 +7/10=13/10=1 i 3/10  = 316|24 = 13 i 4|24
4/15 - 4/15 = 0
b)2 i 9/16 - 1 i 1/4=41/16-20/16=21/16=1 i 5/16

12 i 2|3 + 1 i 3|4 = 38|3 + 7|4 =152|12 + 21|12 = 173|12

 8 i 1|8 - 2|3 = 65|8 - 2|3 = 195|24 - 16|24 = 179|24

c) 6 i 1|4 - 3 i 5|6 = 25|4 - 23|6 = 75|12 - 46|12 = 29|24

7 i 1|6 + 6 i 1|8 = 43|6 + 48|8 = 172|24 + 144|24 = 316

75|12 - 46|12 = 29|12 * = 2 i 5|12

 6 i 1|3 - 3 i 5|6 = 19|3 - 23|6 = 38|6 - 23|6 = 15|6 = 2 i 3|6

 d) 3|8 + 5|6 - 7|12 = 9|24 + 12|24 - 14|24 = 7|24

 2 i 1|6 - 1 i 1|2 + 1|8 = 13|6 - 3|2 + 1|8 = 52|24 - 36|24 + 3|24 = 19|2

5 i 1|14 - 2 i 1|4 - 1 i 3|7 = 71|14 - 9|4 - 10|7 = 142|28 - 63|28 - 40|28 = 39|28 = 1 i 11|28

PAMIĘTAJ  ŻE TO SIĘ SKRACA 

a) 3 * 3|8 = 9|8 = 1 i 1|8
b) 3|5 * 4|7 = 12|35
c) 5|16 * 24 = 120|16 = 7 i 8|16 = 7 i 1|2
d) 2 i 2|9 * 3|5 = 20|9 * 3|5 = 60|45 = 1 i 15|45 = 1 i 1|3
e) 3 i 1|2 * 2 i 4|7 = 7|2 * 18|7 = 126|14 = 9
f) 4 i 4|5 * 3 i 3|4 = 24|5 * 15|4 = 360|20 = 18
g) 4|9 / 8 = 4|9 * 1|8 = 4|72
h) 6 / 2|3 = 6 * 3|2 = 18|2 = 9
i) 1 i 1|8 / 3 = 9|8 * 1|3 = 9|24 = 3|8
j) 8 i 1|3 / 5|6 = 25|3 * 6|5 = 150|15 = 10
k) 4 i 1|5 / 2 i 1|3 = 21|5 / 7|3 = 21|5 * 3|7 = 63|35 = 1 i 28|35= 1 i 4|5
l) 1 i 3|8 / 6 i 3|5 = 11|8 / 33|5 = 11|8 * 5|33 = (tu lepiej skorcic 11 z 33 ( zostaje 1 i 3))
Wiec będzie = 5|24
