In multiplications: the decimal point moves to the right as many steps as the number has zeros.
In divisions: the decimal point moves to the left as many steps as the number has zeros.

\( 1.23\times110=\text{ ?} \)
\( 20.1:10= \)
\( 13.61:10= \)
\( 12.2:10= \)
\( 65.2:10= \)
We will use the distributive property to split 110 into two numbers—100 and 10.
Now we will multiply the original number (1.23) by these two numbers:
1.23*100=123
1.23*10=12.3
All that is left to do is to add the two products together to get our answer:
123 + 12.3 = 135.3
\( 581.8:10= \)
\( 111.1:10= \)
\( 51.4:10= \)
\( 11.31:10= \)
\( 7.81\times10= \)
\( 1.52\times10= \)
\( 2.7\times10= \)
\( 1.4\times10= \)
\( 0.7\times10= \)
\( 2.66\times10= \)
