5/4 rounding usually goes like this:
25.0 ==> 25
25.1 ==> 25
25.2 ==> 25
25.3 ==> 25
25.4 ==> 25
25.5 ==> 26
25.6 ==> 26
25.7 ==> 26
25.8 ==> 26
25.9 ==> 26
OpenStudy (anonymous):
so yes it would stay the same at 25 Correct?
OpenStudy (anonymous):
then 4.65 would round to 5 Correct?
OpenStudy (curiousquestions):
Correct!
OpenStudy (curiousquestions):

"Estimate the product of 25.311 * 4.65"
Well, we multiply the rounded numbers. So, give me the equation of the rounded numbers.
OpenStudy (anonymous):
do i do 25/4 and then round 6.25 to the nearest whole number?
OpenStudy (curiousquestions):
it's 25/5, remember? 4.65 rounds to 5.
OpenStudy (curiousquestions):
and where did you get 6.25?
