Expresse os seguintes valores em unidades do sistema internacional: (a) 12km (b) 15km. (C)260dam (D) 45hm (e) 320cm (f) 4200dm (g) 16min (h) 9h (i) 1200g (j) 5t (k)62t (l)12300g​

Answer 1

(a) 12km = 12000m

(b) 15km. = 15000m

(C)260dam = 260 ×10= 2600m

(D) 45hm = 45 ×100 = 4500m

(e) 320cm = 320/100 = 3,2m

(f) 4200dm = 4200/10 = 420m

(g) 16min = 16 ×60 = 960s

(h) 9h = 9 ×3600 = 32400s

(i) 1200g = 1200/1000 = 1,2kg

(j) 5t = 5000kg

(k)62t 62000kg

(l)12300g = 12300/1000= 12,3kg
