Question

calculati si apoi completati spatiile punctate: a) 23,45g +1,935dag -0,17hg =...dag b) 0,572dg + 0,004g -4mg =...cg c)12,5l + 120cl - 6dl =...dm la puterea 3d) 72kl + 650hl =...m la puterea 3

Answer 1

a)23,45g+1,935dag-0,17hg=0,02345+1,935-1,7=0,02345+0,235=0,25845dag
23,45g=0,02345dag
0,17hg=1,7dag
b) 0,572dg+0,004g-4mg=0,572+0,004-0,4=0,576-0,4=0,176
0,572dg=5,72cg
4mg=o,4cg
c)12,5l+120cl-6dl=12,5+1,2-0,6=13,7-0,6=13,1l=13,1dm³
120cl=1,2l
6dl=0,6
d) 72kl+650hl=72m³+65m³=138m³
72kl=72000l=72000dm³=72m³
650hl=65000l=65000dm³=65m³
