8 can go into 17 twice with one left over so
the answer is 2 1/8
Hope this helps!!!
Type it into Google and it will solve for you.
100^(1/2)-125^(1/3) = 10-5 = 5
Since you didn't list choices, I can only give you some guidance on the problem.
A kilometer is the length of 1000 meters. And a meter is about as tall as a normal desk height. So a kilometer is a relatively long distance compared to a desk.
It is also about half the length of a mile, or about 2 times around a normal athletic track.
Look for items that are long distance like that.
