Answer 1

Odpowiedź:

zad 1

a)

34% = 34/100 = 0,34

15,7% = 157/1000 = 0,157

6,28% = 628/10000 = 0,0628

190% = 190/100 = 1,9

0,9% = 9/1000 = 0,009

5,8% = 58/1000 = 0,058

b)

25% = 25/100 = 1/4

12% = 12/100 = 3/25

60% = 60/100 = 6/10 = 3/5

72% = 72/100 = 36/50 = 18/25

240% = 240/100 = 2 4/10 = 2 2/5

42,2% = 422/1000 = 211/500

zad 2

a)

0,32 = 32%

0,8 = 80%

2,1 = 210%

0,036 = 3,6%

7,02 = 702%

16 = 1600%

b)

2/5 =4/10 = 40/100 = 0,40 = 40%

2 1/4 = 2 25/100 = 225/100 = 225%

7/8 = 875/1000 = 0,875 = 87,5%

3/20 = 15/100 = 0,15 = 15%

1 2/25 = 1 4/100 = 104/100 = 104%

5/2 = 250/100 = 2,5 = 250%

c)

2/3 = 200/3% = 33 1/3 %

1/6 = 100/6% = 16,(6)%

2 1/3 = 700/3 % = 233,(3)%

5/11 = 500/11% = 45,(45)%
