ok
1) -2.5, 0.11111...., 1/4, 5 4/5, sqrt51, sqrt 100
2) Using simplification,
-2.5 is smallest because its negative, and no other number is negative. 0.11111 is the second smallest
1/4 is 0.25, and the third smallest
5 4/5 is 5.8 and is the third biggest
sqrt of 51 is around 7.14, so its second largest
lastly, sqrt 100 is 10, making it the largest
3) 10-(-2.5)=12.5
