Question

35 m in hm plus 40 dam in hm plus 3 hm

7dam in hm plus 50 m in ham plus 90 ham

Answer 1

7dam=0,7hm
50m=0,5hm

90+0,7+0,5= 91,2hm

Answer 2

deci avem o problema de multipli ai metrului
m      = metru                               = 10⁰m
Dam  = Decametru = 10              = 10¹m
Hm    = Hectometru = 100            = 10²m
Km    = Chilometru  = 1000          = 10³m
Mm    = Megametru = 100000      = 10⁶m
Tm     = Terametru  = 100000000 = 10⁹m

35 *10⁰ + 40 * 10¹ + 3 * 10² = ( 35 * 10⁻² +  40 * 10⁻¹ + 3 * 10⁰ ) * 10² = 7.35 * 10²m = 7.35Hm
7 * 10¹ + 50 * 10⁰ + 90 *10² = ( 7 * 10⁻¹ + 50 * 10⁻² + 90 * 10⁰ ) * 10² = 91.2 * 10²m = 91.2Hm
