Question

1. 21 l - 180 l = ............ ml. 2. 46.000 ml + 2.800 dl = ............ l. 3. 40 dm3 + 1 dal - 30.000 cm3 = ............. l

Answer 1

1. 21 l - 180 l = (21x1.000)-(180x1.000) = 21.000 ml-180.000 ml
2. 46.000 ml + 2.800 dl = (46.000:1.000)+(2.800:10) = 46 l+280 l = 326 l
3. 40 dm³+1 dal-30.000 cm³ = (40x1)+(1x10)-(30.000:1.000) = 40 l+10 l - 30 l = 50 l -30 l = 20 l

(yg no 1 maaf ya gk dijawab,soalnya salah mungkin...)
