by "subtracting" or crossing out equal-size groups from the total in the visual model, until there is nothing left.
yes :) thanks ... can you help me with some more questions please? @Falling_In_Katt
I can try
Can you divide by zero? Why or why not?
Division 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.
@geny55, What do you understand now about division by zero that you didn't before?
i just didnt get why you coudnt divide by 0
But what did you learn about why you can't divide by 0?
that it would be undefined :) and you cant do it because it would just give you 0
How do you change a rational number to a decimal? Can you give an example of each?
I can tell you how. Then you try to make examples.
Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.
so now i do the example?
Try to do this -Express 7 / 8 rational numbers to decimals form by long division method
@geny55 what does ''undefined" mean to you in terms of division by zero?
i got 1.14285714
That's wrong. Here ill set the equation up for you. \[7.000 \div 8\]
can i do 17 / 8 instead please
You would get the wrong answer, you must use long division! Be sure to show your steps.
if 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
so whats the problem again?
Express 7 / 8 rational numbers to decimals form by long division method.
do you know how to do long division geny ?
Set it up like \[7.000\div8\]
even when you have to add a decimal and zeros
its just simple division....if you know long division, then you already know this
you did 8/7 ,Geny
oh, whoops.. sorry
its 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 ?
correct.....so 7/8 as a decimal is 0.875
nicely done :)
thanks i have somoe more questions :) please stay :)
this is the last question :) Explain how to write repeating decimals in proper form?
