140/84 = 5/3
It is: 84/72 = 7/6 simplified
3/7
4/3
7/12
Divide each part by 42, to give 2 over 5.
Leave it exactly as it is 84
42 over 59. You cannot simplify 59 any further.
You divide both parts by their highest common factor, which is 28. That gives you 2 over 3.
That is in its simplest form. You can't simplify sqrt(166) any more then it is. The decimal approximation can be found by (166)^1/2
1/3
A percentage always relates to 100, so in this case it would be 84 over 100. Their greatest common factor is 4, so you can simplify it down to give 21 over 25.
