What do you call a decimal whose digits do not go on forever?
A terminating decimal number.
Why do you move your decimal when multiplying?
"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.
What number does 8 and 15 all go into?
120 (which can be found by multiplying 15 and 8)
Who to write decimal number?
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
Is 2.434434443 a rational number?
Yes, if the decimal doesn't go on forever, then it is a rational number.
How do you convert decimal to percent?
times it by 100 e.g. 0.5 = 50% (0.5 x 100 =50)
What is 0.00009 as a percent?
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.
When multiplying 1.0400 x 0.302001 the number of significant figures in the answer should be?
5 since 1.0400 has 5 significant figures. when dividing or multiplying go with the number with the smaller significant figures.

It can go anywhere.
How can you determine the number of decimal places in your your final answer when multiplying with deciamles?
oh its quite simple, lets say you have a problem like 12.5 times 2.5 first you would find how much this is which would be 3125. then to find the decimal place, just count how many spaces are in each factor (12.5 and 2.5) as you can see, the decimal in 12.5 is one space that way <. and in 2.5 the decimal is also one space that way <. so how many spaces are there? two spaces! now we go back to 3125. if we were to place the decimal, we would first count up to how many spaces there are to the left (in this case two spaces) then we would go back to our answer and count two spaces to the left: 31.25! we started out with 3125 and to find the decimal place we started before the five and counted two spaces to the left which would be < that way! ta da!
