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.
Three. Count number of zeros. If multiply decimal by 100 move decimal point 2 places, etc.
If you multiply a number by 100%, you are simply multiplying by 1. You can multiply by 100% to change a decimal number or fraction to a percent. (0.25)(100%)=25%. You can also divide by 100% to change a percent to a decimal number. 65%/100%= 65/100 or 0.65.

The difference is that if you multiply with a whole number and then multiply with a decimal and you compare.You will notice the whole number is greater.You are very welcome.
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
whenever you multiply a whole number by a decimal you get a decimal. 2.9x100=290
Three. Count number of zeros. If multiply decimal by 100 move decimal point 2 places, etc.
you multiply by 2
You usually get another number!
True
Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.
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.
The answer depends on what the decimal is.For example, 4 * 3.5 = 14But 4 * 3.6 = 14.4
This is not necessarily true. 2 x 0.55 = 1.1
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.
False. 2 x 0.55 = 1.1
