-- 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.
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
The answer depends on what the decimal is.For example, 4 * 3.5 = 14But 4 * 3.6 = 14.4
To multiply a whole number by a decimal, you can simply multiply the whole number by the decimal as if it were a fraction. First, ignore the decimal point and perform the multiplication. Then, count the number of decimal places in the decimal and adjust the result by moving the decimal point to the left that many places. For example, when multiplying 5 by 2.3, calculate 5 × 23 = 115, and then move the decimal point two places to the left, resulting in 1.15.
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.
Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.
3.14 times 196 is equal to 615.44. This calculation is done by multiplying the decimal number 3.14 by the whole number 196. To find the product, you multiply the whole number by the whole number part of the decimal (196 x 3) and then multiply the whole number by the decimal part (196 x 0.14) before adding the two products together.

3.14 times 10 equals 31.4. This is because when you multiply a decimal number by a whole number, you simply move the decimal point of the decimal number to the right the same number of places as there are zeros in the whole number. In this case, 3.14 times 10 is 31.4.
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.

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.
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.
whenever you multiply a whole number by a decimal you get a decimal. 2.9x100=290
You multiply the whole number as many times as the exponent is.
... less than the whole number.
