37/1000. 37 is a prime number and does not evenly divide into 1000, therefore this fraction can not be simplified.
already lowest 7 is a prime number and does not divide evenly in to 12 so answer is still 7/12
Because no other number that is the same will divide into both of those numbers evenly, it is in simplest form, eg. 4 over 6 can be simplified to 2 over 3 because 2 divides evenly into 4 and 6. * * * * * The above answer is wrong because 3 WILL divide into both of those numbers evenly. 39/45 = (3*13)/(3*15) = 13/15
You can tell that 4/5 is in its simplest form because 5 is a prime number. The 5 is not evenly distributed unless it is by itself or the number 1.
0.5
No. 151 is a prime number and as it does not evenly divide into 320 we know this can not be simplified.

What I do is start with 2's and 5's because they're easiest, since every even number is evenly divisible by 2 and every whole number ending in 5 or 0 is evenly divisible by 5. Then I start from 3 going through the prime numbers, dividing the remaining part of the number by each prime number on a calculator to see if the quotient is a whole number. I continue whittling away at the number in that way with each prime number in order until the quotient I get is less than the prime number divisor I tried; at that point I know that what's left over must be a prime number.
No, it cant. 13 is a prime number, so only 1 and itself can go into it. 13 cannot go into 25 evenly. :)
17 over 54. 17 is a prime number, which can only be divided by itself and one. It does divide evenly into 54.
9000 and none left over
It means, it is a number which can be divided evenly into the larger number, an even number of times. Example 2 divides into 6 , 3 times evenly, a nice whole number like 3 which is what we are looking for. Not something like 3 1/8 or 3 1/2 times this over hanging fraction like what was just stated 3.125 or 3.250 would not be a whole nice number. But with some left over portion of a number we don't desire. Its the .125 or .250 part that bug us.
