Denise walked 106.95 miles in July.
Denise walk every afternoon
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
