Best ResponseYou've already chosen the best response.0Can you divide by zero? Why or why not?

Best ResponseYou've already chosen the best response.0Division by zero is an operation for which you cannot find an answer, so it is disallowed. You can understand why if you think about how division and multiplication are related. 12 divided by 6 is 2 because 6 times 2 is 12 12 divided by 0 is x would mean that 0 times x = 12 But no value would work for x because 0 times any number is 0. So division by zero doesn't work.

Best ResponseYou've already chosen the best response.0Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.

Best ResponseYou've already chosen the best response.0That's wrong. Here ill set the equation up for you. \[7.000 \div 8\]

Best ResponseYou've already chosen the best response.0You would get the wrong answer, you must use long division! Be sure to show your steps.

Best ResponseYou've already chosen the best response.0if you have to show your work by using long division, then just using a calculator to do it will not work. However, you can use a calculator to check your answer

Best ResponseYou've already chosen the best response.0its easy to get confused on that....the numerator is in the box, the denominator is what you are dividing by and is outside the box...understand ?
