-- 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
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.
Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.

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.
Example of multiplying whole decimal numbers: 2.37 × 3.56 = 8.4372 Remove the decimal point and multiply as for whole numbers: 237 × 356 = 84372 Then add the decimal point, thus : 8.4372
To express .20 as a whole number, you would multiply it by 100 to shift the decimal two places to the right. This would give you 20 as a whole number. Converting a decimal to a whole number involves removing the decimal point by multiplying the decimal by the appropriate power of 10.
A decimal, in this context, is a useless description: a decimal can be an integer, a rational number or an irrational number. Furthermore, a whole number times a decimal fraction can be a whole number, a rational number or an irrational number.For example:4 * 3.5 = 14 is a whole number times a decimal fraction = whole number.4 * 3.3 = 13.2 is a whole number times a decimal fraction = rational fraction.4 * 3.14159... [ie pi in decimal form] = 4 * pi, which is an irrational number.
