To multiply a whole number and a decimal by multiplying without a decimal point first, then on the answers, just put the total decimal place
Decimal numbers are numbers in which there are commas or decimal points.
The value of each number in decimal numbers is based on a comparison of the number 10 (base ten)
In a decimal system, the numbers have the following consecutive values (the place value of the digits in a number): hundred thousands, ten thousands, one thousands, hundreds, tens, ones, decimal points, tenths, hundredths, thousandths, ten thousandths , hundred thousandths etc.
Between ones and tenth values separated by commas (decimal points)
Decimal numbers can also be expressed as proper or mixed fractions
The position of each digit in decimal numbers is important.
Because the decimal number is based on the number 10, As we move left, each position is 10 times bigger, and As we move right, each position is 10 times smaller
On the left of the decimal point is a whole number
In the arithmetic operation of the decimal number multiplication, we can do it first as a multiplication between ordinary numbers without the comma (decimal point)
After we get the multiplication results, we count the number of decimal places of the multiplied number
Example:
0.92x6
92x6 = 552
0.92 = has two decimal places
6 = has no decimal places (whole number)
total decimal places = 2
The comma (decimal point) of the number 552 we move from right to left by 2 (according to the total decimal places of the 2 numbers multiplied above), becomes
