Multiplying and Dividing Decimal Word Problems

To divide a decimal by a whole number, move the decimal point in the dividend (the number being divided) to the right as many places as needed to make it a whole number. Then, divide as you would with whole numbers and place the decimal point in the quotient (the result) directly above where it is in the dividend.

To multiply a decimal by a whole number, multiply as if there were no decimal point. Then, count the total number of decimal places in the decimal factor and place the decimal point in the product accordingly.

The area of a rectangle is found using the formula: Area = Length × Width.

To find the width, use the area formula: Width = Area ÷ Length. So, Width = 128 ft² ÷ 12.5 ft = 10.24 ft.

Sharing costs equally means dividing the total cost by the number of people sharing it, so each person pays the same amount.

To calculate the total cost, multiply the price of one item by the number of items purchased. Total Cost = Price per Item × Number of Items.

Decimal places indicate the precision of a number. In multiplication, the total number of decimal places in the product is equal to the sum of the decimal places in the factors.

To convert dollars to cents, multiply the dollar amount by 100. For example, $2.50 = 2.50 × 100 = 250 cents.

The total earnings can be calculated by multiplying the hourly wage by the number of hours worked. Total Earnings = Hourly Wage × Hours Worked.

To find out how many items you can buy, divide the total amount of money by the price of one item. Number of Items = Total Money ÷ Price per Item.
