Wyraź:
a) w litrach: 9 dm3 3000 ml 4500ml 250 ml 34 ml
b) w mililitrach: 8 l 9,5 l 4 dm3 7,2 dm3 81 cm3 527 cm3
c)w decymetrach sześciennych: 15 l 3,7 l 8000 cm3 6000ml
Proszę o rospisywanie działań musze mieć to na dziś plliss!
to są regułki:
1l = 1 dm3
1 l = 1000 ml
1 ml = 1 cm3
1 dm3 = 1000cm3

a) w litrach:
9 dm3 = 9 l
3000 ml = (3000 : 1000) l = 3l
4500ml = (4500 : 1000) l = 4,5l
250 ml = (250 : 1000) l = 0,25l
34 ml = (34 : 1000) l = 0,034l
b) w mililitrach:
8 l = 8 * 1000ml = 8 000ml
9,5 l = 9,5 * 1 000ml = 9 500ml
4 dm3 = 4 l = 4 * 1 000ml = 4 000ml
7,2 dm3 = 7,2 l = 7,2 * 1 000ml = 7 200ml
81 cm3 = 83 * 1ml = 83ml
527 cm3 = 527 * 1ml = 527ml
c)w decymetrach sześciennych:
15 l = 15 * 1dm^3 = 15dm^3
3,7 l = 3,7 * 1dm^3 = 3,7dm^3
8000 cm3 = (8 000 : 1 000)dm^3 = 8dm^3
6000ml = (6 000 : 1000) l = 6 l = 6 dm^3
