Walk 3.45 miles/day on July

How far did Denise walk during the month of July?

we know that the month of July has 31 days, so to find out how far Denise walked in that month :

=mileage/day x the number of days in July

= 3.45 x 31

= 106.95 miles

So, Denise walked 106.96 miles in July

Here step by step to do decimal multiplication :

3.45                ⇒ has 2 decimal place

  31 x             ⇒ has no decimal place

345

1035 +

106.95            ⇒ has 2 decimal place  

From the example above, to do the decimal multiplication we don't need to line up the decimal point. The process is the same way as the whole numbers multiplication except for the placement of the decimal point in the answer.

The first factor has 2 decimal place

Second factor has 0 decimal place

The answer would have 2+0 = 2 decimal place
