PILNE NA DZIŚ! Z GÓRY DZIĘKI!

Answer 1

a) 9/4 - 5/3 = 27/12 - 20/12 = 7/12

b) 9/2 - 13/5 = 45/10 - 26/10 = 19/10

c) 29/9 - 11/6 = 174/54 - 99/54 = 75/54

d) 8/3 + 3/2 - 11/6 = 16/6 + 9/6 - 11/6 = 14/6

e) 25/6- 8/5 + 5/2 = 125/30 - 48/30 + 75/30 = 152/30

f) 13/4 - 13/5 + 17/10 = 65/20 - 52/20 + 34/20 = 47/20

Answer 2

2 3/4 - 1 8/4 = 1 11/4  - 1 8/4 = 3 / 4
4 1/2 - 2 3/5 = 4 5/10 - 2 6/10 = 3 16/10 - 2 6/10 = 2

3  2/9 - 1  5/6 =  3 12/54 - 1 45/54 = 2 66/54 - 1 45/54 = 1 11/54
2  2/3 + 1 1/2 - 1  5/6= 2 4/6 + 1 2/6 - 1 5/6 = 3 6/6 - 1 5/6 = 2 1/6
4  1/6 - 1 3 /5 + 2  1/2= 4 5/30 - 1 18/30 + 2 1/2 = 3 65/30 - 1 18/30 + 2 1/2 = 2 47/30 + 2 1/2 = 3 17/30 + 2 15/30 = 6 2/30

3  1/4 - 2 3/5  +  1 7/10= 3 5/20 - 2 12/20 + 1  7/10 = 2 25/20 - 2 12/20 + 1 7/10 = 3/20 + 1 7/10 = 3/20 + 1 14/20 = 1 17/20

mam nadzieje , że pomogłam ; D
