-- Ignore the decimal point; just multiply the two whole numbers.
-- After the multiplication is done, put the decimal point back into the product.
Put it in the right place so that the product has as many digits after the point
as the original decimal had. If there aren't enough digits in the product to do
that, add some zeros to the left end of it.

If you multiply a decimal number and a whole number will you have a decimal in the answer?
Often, yes. But it depends on the numbers. For example, if you multiply 1.5 x 2, you get 3 as the answer (whole number). But if you multiply 1.5 x 3, you get a decimal of 4.5
What is the difference between multiply a whole number by a whole number and multiply a whole number by a decimal?
The answer depends on what the decimal is.For example, 4 * 3.5 = 14But 4 * 3.6 = 14.4
How dividing by decimal is different from dividing by whole number and how it is similar?
Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.
How do you multiply a whole number by a decimal in the hundreths?
When multiplying a whole number by a decimal with two places, ignore the decimal point and multiply as if you were multiplying two whole numbers. After you get the answer, re-insert the decimal point so that the product has two decimal places.
What is 2 times 0.8?
2 times 0.8 is equal to 1.6. When you multiply a whole number by a decimal, you simply multiply the whole number by the digits after the decimal point. In this case, 2 multiplied by 0.8 equals 1.6.
