A terminating decimal number.
"Moving the decimal point" is an easy way to accomplish some multiplications or divisions. If you have a number and you need to multiply it by 10, you should go through the process of multiplication as you've learned to do it, and then when you finish, LOOK at the product you've produced and SEE that it's the same as the original number but with its decimal point moved one place to the right. Then, forever after, you'll remember that if you need to multiply a number by 10, simply move its decimal point one place to the right, and your multiplication will be done. If you have a number and you need to divide it by 10, you should go through the process of division as you've learned to do it, and then when you finish, LOOK at the quotient you've produced and SEE that it's the same as the original number but with its decimal point moved one place to the left. Then, forever after, you'll remember that if you need to divide a number by 10, simply move its decimal point one place to the left, and your division will be done.
120 (which can be found by multiplying 15 and 8)
To write a decimal you go to the end of the whole number 5 for example and then you put a period (5.) then you add the rest of the decimal like 5.6
Yes, if the decimal doesn't go on forever, then it is a rational number.
times it by 100 e.g. 0.5 = 50% (0.5 x 100 =50)
a terminating decimal, like 0.75
A terminating decimal number.
To get the percentage of any number, you multiply the number by 100. So the percentage of 0.00009 is (0.00009)(100) = 0.009% ----------------------------------------------------------------------------------- Let's look at it another way. We want to change the decimal fraction 0.00009 to a percentage. In the case of decimals all you have to do is to move the decimal point 2 places to the right - but why? Well, you must agree that anything multiplied by 1 does not change the "anything", but we want to multiply by 1 in a special way, and that is by multiplying the "anything" by 100%. Again, if you multiply a decimal by 100 the point needs to go 2 places to the right. Now, of course it is a percentage and must have the % sign. What was a decimal fraction has become a percentage fraction.
After the 5!
ALWAYS Between the units number and the tenths decimal number. e.g. 4.5 '4' is the units ' 5' is the tenths decimal number. or 345 '2' is the units number and ;3; is the tenths decimal number. When adding or subtracting decimals keep the decimal point directly below each other. It makes for far easier manipulation Hence (adding) 102.345 004.500 (Note the use of trivial zeroes '0'. ____----- 106.845 ====== Rather than 102.345 4.5 Much more difficult and far easier to make a mistake.

To turn 13 percent into a whole number, you need to multiply 13 by 100 to convert it to a decimal form. This gives you 0.13. To convert this decimal into a whole number, you need to multiply it by a power of 10 that will shift the decimal point two places to the right. Therefore, multiplying 0.13 by 100 gives you 13 as a whole number.
5 since 1.0400 has 5 significant figures. when dividing or multiplying go with the number with the smaller significant figures.

The ten place is the first number to the right of the decimal.
It can go anywhere.
