Calculați :5 km+8 dam+30m=...dam=...m; 20 km+5000 m+14 km=... km=... hm; 8000 cm-12 m+20 dm=... m; 2 km x 3-35m x 7+250dm=...m; 35km:7-25m x 8+75dm x 6=...m. Ajutați-mă vă rog!
a)5000m+80m+30m=5120m=512dam ....b)20km+5km+14km=39km=390hm.....c)80m-13m+2m=69m.....d)6km-245m+25m=6000m-245+25=5780m, e)5km-200m+450dm =5000m-200m+45m=4845 m. am efectuat direct operațiunile necesare sper sa înțelegi
