Exercises: multiplying decimal numbers

As soon as you "pull down" the $1$ after the decimal point on the left, you also have to put a decimal point in the result on the right.

$\begin{array}{l}\phantom{-}8.1:9=0.9\\ \underline{-0}\\ \phantom{-}81\\ \underline{-81}\\ \phantom{-8}0\end{array}$

As soon as you "pull down" the $5$ after the decimal point on the left, you also have to put a decimal point in the result on the right.

$\begin{array}{l}\phantom{-}7.5:2=3.75\\ \underline{-6}\\ \phantom{-}15\\ \underline{-14}\\ \phantom{-1}10\\ \phantom{0}\underline{-10}\\ \phantom{-10}0\end{array}$

As soon as you "pull down" the $4$ after the decimal point on the left, you also have to put a decimal point in the result on the right.

$\begin{array}{l}\phantom{-}29.48:11=2.68\\ \underline{-22}\\ \phantom{-2}74\\ \phantom{0}\underline{-66}\\ \phantom{-66}88\\ \phantom{88}\underline{-88}\\ \phantom{-888}0\end{array}$

As soon as you "pull down" the $8$ after the decimal point on the left, you also have to put a decimal point in the result on the right.

$\begin{array}{l}\phantom{-}13.811:7=1.973\\ \phantom{0}\underline{-7}\\ \phantom{-0}68\\ \phantom{0}\underline{-63}\\ \phantom{-00}51\\ \phantom{00}\underline{-49}\\ \phantom{-000}21\\ \phantom{000}\underline{-21}\\ \phantom{-0000}0\end{array}$
