If you’re talking centimeters, the answer rounded to the nearest tenth would be 2.8 cm.
If you’re talking inches, the answer rounded to the nearest 16th would be 2 and 13/16 inches. But if your inch ruler only goes up to eighths, then the answer would round up to 2 and 7/8 inches.

8 1/2 divided by 3 =
17/2 divided by 3 =
17/2 (1/3) = 17/6 = 2 5/6
So on a ruler which is section off with 1/32, it is just below 2 28/32, or 2 7/8

8 1/2 DIVIDED BY 3
If they are both in inches, the answer is 2 5/6 inches
8 1/2 = 17/2 ( (2 x 8 + 1/2)
17/2 divided by 3
In dividing fractions, just multiply the first term by the reciprocal of the second term,
the reciprocal of 3 is 1/3
17/2 x 1/3 = 17/6
In mutiplying fractions, just multiply the numerator of the first term by the numerator of the second term and multiply the denominator of the first term by the denominator of the second term.
17/6 ==> convert to mixed fraction
To convert improper fraction to mixed fraction, normally divide the numerator by the denominator. Write the whole number followed by the remainder over the denominator
17/6 = 2 remainder 5
17/6 = 2 5/6 ==> the answer

To divide 8.5 by 3 what you need to do is first draw a line of length 8.5 (say OA) then draw another line at an acute angle to this line from point O and name it OB such that OB=3cm. Now draw AB.
On line OB mark points C and D such that OC=CD=DB=1cm.
Now from Points C and D draw lines parallel to AB intersecting OA thus you have 8.5 divided into 3 equal parts

This might be a normal answer: 2.83
8.5 divided by 3 = 2.83

2 & .833 inches..
so…
approximately 2 and 8/9.6 inches..
or more like 2 and 8/10 if rounded up

your answer is 2 5/6 or 2.83

The precise answer is 2.83333333333333333 (with 3’s carrying on ad infinitum)
Another way of thinking of it is as twoandfivesixths
