• in do you have to put the zeros? I'm just making sure.
• Also think of it this way: 540.0 =540.0000000000
• what do i do when i can not concentrate when my friends are talking?
• tell them, ''be quiet, please'' :]
• is it possible to make 1000000000000000 in a fraction
• I think so it would be like 1000000000000000/1
• at do you need the zeros
• Since adding as many zeroes as wanted behind the decimal point (for example 7 = 7.0000000) never changes the number, one can do it. You don't need the zeroes, but the problem is a lot easier if you add them.
• I have a math problem it is 40 divided by 1.25. This video didn't really help me with this problem but if any of you guys know how to help me please leave a comment. Thanks
• Just move the decimal 2 places to the right so it becomes 4000 divided by 125.
• why do we put the decimal point there?
• Do we have to move the decimal how many times we moved the decimal at first? On , this question makes it hard to understand what you did.
• Why would you multiply by 10? Why, not 100?
