Question

zamiana jednostek:

1/2 h = s

4 h = s

0,02 h = s

0,25 h = s

1/2 min = s

0,25 min = s

60 s = h

7200 s = h

1800 s = h

180 s = h

/ ---- krska ułamkowa

Answer 1

1/2 h = 1800s

4 h = 14400s

0,02 h = 72s

0,25 h =   900s

1/2 min =  30 s

0,25 min =  15 s

60 s =   1/60h

7200 s =   2h

1800 s =  1/2 h

180 s =  1/30 h

Answer 2

1/2h = 1800s

4h = 14400s

0,02h = 72s

0,25h =   900s

1/2min =  30s

0,25min =  15s

60s =   1/60h

7200s =   2h

1800s =  1/2h

180s =  1/30h
