Exercise #1

1.23×110= 1.23\times110=

Video Solution

Step-by-Step Solution

We will use the distributive property to split 110 into two numbers -

100 and 10

 

Now, we'll multiply the original number, 1.23, by these two numbers.

1.23*100=123

1.23*10=12.3

 

All that's left to do is to add the two products we got - 

123+12.3=

135.3

 

And that's the solution!
