Answer:
31 is a prime number.
How to tell if a number is prime: estimate the square root. In this case, we know the square root of 31 is between 5 and 6 and it isn’t divisible by either of those. If it is divisible by a number higher than it’s square root, the other factor must be lower. Is it divisible by 4 or 2? no, because it isn’t an even number. It’s not divisible by 3, because there’s a remainder of 1 if you try. You’ve eliminated all numbers less than the square root, so it is prime
159.2/3.2=49.75
take 159.2 and divide it by 3.2 and you get 49.75
to check your answer you would take 159.2 divided by 49.75
159.2 divided by 49.75 = 3.2
3.2 is 49.75 percent of 159.2
