No. 151 is a prime number and as it does not evenly divide into 320 we know this can not be simplified.
19/40 is in the reduced form as there is no whole number that divides 19 and 40 evenly (remainder zero).
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
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.
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
No, it cant. 13 is a prime number, so only 1 and itself can go into it. 13 cannot go into 25 evenly. :)
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.
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
