22/7 is 3.143, to 3 d.p.
As other ABers have explained, 22/7 is only a fairly inaccurate approximation to pi.
355/113 is probably more than close enough for most purposes.
because each column equates to a number. In our system of counting (base 10) we use these columns: thousands, hundreds, tens, units and so on. Each column to the left is 10 times the one on the right. The number 763 indicate 7 hundreds, 6 tens and 3 units.
Binary is base two and so the columns go 16,8,4,2,1 The number 101010 equals 1x32 1x8 and 1x2
// So what exactly do you think a ratio is, if not one number divided by another ? //
A ratio is a relationship between two numbers of the same type.
usually expressed as follows... 22 : 7
Pi is a single number, but ok, I agree you can use that number to express the ratio between 22 and 7.
I'm just trying to provoke an interesting debate. I'm implying that whoever designed the circle got it slightly wrong - they should have made the circumference exactly 3 times the diameter, which would have been a much cleaner solution.
How can you make the circumference of a circle exactly three times it's diameter? It wouldn't be a circle. You might as well ask why not make a square with 4 different length sides.
3.14 : 1 is the ratio of the diameter to the circumference. It is a ratio.
