Greg will need $2.08 more money to buy 12 gallons of gas.
<h3>
Further explanation</h3>
A gallon of gas costs $4.34
Greg puts 12 gallon of gas
Greg has $50
First, we are going to calculate how much money does Greg needs for 12 gallon of gas:
= 12 gallon of gas x cost/gallon
= 12 x 4.34
= 52.08
To multiply the decimal it's just the same way as the whole number multiplication, except for the placement of the decimal point in the answer. For the example
4.34 ⇒ 2 decimal place
<u> 12 x</u> ⇒ 0 decimal place
868
<u>434 +</u>
52.08 ⇒ 2 decimal place
By doing the same process as the whole number multiplication we got the answer is 52.08, but don't forget to add the decimal point/decimal place. The first factor has 2 decimal place, the second factor has 0 decimal place, so the answer will have two decimal place (2+0 = 2), by adding the decimal place.
The next step , 12 gallon of gas cost $52.08, if he has $50 so it cost more than the money he has, We are going to do a subtraction:
$52.08
<u>$50.00 </u>- ⇒ <em>we put zero so we can the borrowing (regrouping)</em>
$ 2.08
To subtract a decimal number, we need to line up the decimal point, add trailing zero as a placeholder and then do the subtraction
