Look at the square root like "x", then
4 + 4 + 4 - 1 = 11? Was it supposed to be an equation? I am confused.
Answer:
Natural numbers are the counting numbers, meaning that they make up the set {1,2,3,4,5,...} So , 4/5 is belong to natural number
If the problem did not give you the percentile it would be confusing. You would not know if they wanted money or just a number!!! So it is pretty important.
