Pembahasan

Pertanyaan ini berkaitan dengan konversi satuan panjang dalam sistem metrik.

1.  $3 kl + 7 hl = ... dal$
    *   1 kiloliter (kl) = 10 hektoliter (hl)
    *   1 hektoliter (hl) = 10 dekaliter (dal)
    *   Jadi, 1 kl = 10 hl = 100 dal.
    *   $3 kl = 3 \times 100 dal = 300 dal$.
    *   $7 hl = 7 \times 10 dal = 70 dal$.
    *   $3 kl + 7 hl = 300 dal + 70 dal = 370 dal$.

2.  $6 l + 9 dl = ... ml$
    *   1 liter (l) = 10 desiliter (dl)
    *   1 desiliter (dl) = 100 mililiter (ml)
    *   Jadi, 1 l = 10 dl = 1000 ml.
    *   $6 l = 6 \times 1000 ml = 6000 ml$.
    *   $9 dl = 9 \times 100 ml = 900 ml$.
    *   $6 l + 9 dl = 6000 ml + 900 ml = 6900 ml$.

3.  $3 hl + 5 l = ... dl$
    *   1 hektoliter (hl) = 100 desiliter (dl)
    *   1 liter (l) = 10 desiliter (dl)
    *   $3 hl = 3 \times 100 dl = 300 dl$.
    *   $5 l = 5 \times 10 dl = 50 dl$.
    *   $3 hl + 5 l = 300 dl + 50 dl = 350 dl$.

4.  $7 dal + 9 l = ... cl$
    *   1 dekaliter (dal) = 100 centiliter (cl)
    *   1 liter (l) = 100 centiliter (cl)
    *   $7 dal = 7 \times 100 cl = 700 cl$.
    *   $9 l = 9 \times 100 cl = 900 cl$.
    *   $7 dal + 9 l = 700 cl + 900 cl = 1600 cl$.
