Understand the problem

$1.23\times110=\text{ ?}$

Step-by-step solution

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
