domebotnos · Answer

To the right of the decimal point it is different.  You count tenths, hundredths, thousandths and so on.

1)  0.071811 needs to be rounded off to the nearest 1 hundredth.  That would mean dropping all the final digits except for the two immediately to the right of the decimal point.  Care to try that?

rock_mit182 · Answer

lol I'm embarresed cause is such an elemental thing

rock_mit182 · Answer

but i need to respiond exactly

anonymous · Answer

two question marks are two digits so you... 0. ? ?

rock_mit182 · Answer

so it would be 0.08 and 1.74 ?

mathmale · Answer

Try this:  0.07     followed by 1811 (actually, that's 0.001811).  Is 1811 more than, equal to or less than 5000?

anonymous · Answer

first one, no... second one, yes

domebotnos · Answer

A. is 0.07 and be is 1.74

domebotnos · Answer

*b

mathmale · Answer

the rounding rule states that if the next digit to the right of the 2 we want to keep is 5 or greater, then round UP; if less than 5, round down.  So, try again.  Look what domebotnos has done in the first case.

mathmale · Answer

Can you, rock_mit, explain why domebotnos decided to write 0.07 instead of 0.08?

rock_mit182 · Answer

cause the next digit is greater than 5 so we aprox

rock_mit182 · Answer

sorry, I'm running out of of time, I'm agree with hello123 thanks a lot guys

rock_mit182 · Answer

@hello1213 so the answer is it right ?

rock_mit182 · Answer

i cannot fail

mathmale · Answer

"cause the next digit is greater than 5 so we aprox"   is not correct.  You are to round off to 2 decimal places.  The given 2 decimals are found in 0.07.  What follows is 18ll, which is NOT 5 or greater.  Thus, we drop the 1811 and have the answer:  0.07.

mathmale · Answer

Try (b) again.  See if you can explain your reasoning.

mathmale · Answer

I see 1.74 followed by 07.  What does the rule say we should do?

rock_mit182 · Answer

i got it now so if i have 0.079 then i could wite out 0.08 ?
