Question

Ma ajutati va rog cu calculele astea?! :
148km-1km+240dam+50=.................dam
2600cm+1700mm-15m=.............dm
372dm patrati +2,2 dam patrati- 0,05hm patrati=?dam patrati
259km cub+ 2,53km cub+4,211km cub=?km
18 m cub+2,03 dam cub-759000dm cub=? m cub va rog am mare nevoie dau coroana

Answer 1

148km-1km+240dam+50dam(?)=148000dam-1000dam+240 dam+50dam=147000dam+290dam=147290dam
sper ca e bine

2600cm+1700mm-15m =260dm+17dm-150dm=277dm-150dm=127dm
sper ca e bine .

372dm²+2,2dam²-0,05hm²=3,72dam²+2,2dam²-5dam²=2,92dam²+5dam²=7,92dam²(nu stiu dacă e bine)
