Which pattern describe how the decimal point moves when you multiply a decimal number by any power of ten?
Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Multiplying by a negative power of ten moves it to the left. For example, the -3 power of 10 is 1/1000; multiplying by that moves the decimal point 3 places to the left.
What else can I help you with?
How many places do you have to move the decimal point to multiply a decimal number by 1000?
Three. Count number of zeros. If multiply decimal by 100 move decimal point 2 places, etc.
What is 2.54 multiplied by 5?

How do you make .20 as a whole number?
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.
When you multiply a decimal by a power of ten what is the relationship between the number of places the decimal point moves and the number of zeros in the power of ten?
One to one
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

This is not necessarily true. 2 x 0.55 = 1.1
Explain how to multiply a whole number by a decimal in the hundredths?
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.
