According to the given data, we have the following numbers to order:
3, 1.5%, π, √4, -1 3/4, -157%
To order them from greatest to least, we use logic and common sense as follows:
Number 3 is in this case no problem.
1.5%. This number is express as a percentage, hence, when you have a percentage you have to divide the coefficient to 100, therefore in this case would be 1.5/100 and this is equal to 0.015
π. The number pi is equal mathematically to 3.14159 26535
√4=2
-1 3/4= -1 * 0.75=-0.75
-157%=-157/100=-1.57
Therefore, given the results calculated above, the order from greatest to least would be:
π, 3, √4, 1.5%, -1 3/4, -157%
