Is 5 a factor of 42?
No, 5 is not a factor of 42. A factor of a number divides it evenly with no remainder. When you divide 42 by 5, it does not divide evenly and leaves a remainder of 2. Therefore, 5 is not a factor of 42.
How can you tell 4 over 5 is simplest form?
4/5, do you see a common whole number that will evenly divide (with zero remainder) 4 and 5. The answer is "NO", so 4 over 5 is in its simplest form.
How can you tell that 4 over 5 is in simplest form?
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.
Reduce 5 over 10 to the lowest terms?
To reduce a number to its lowest terms, you have to divide both the numerator and the denominator by their greatest common factor (the largest number that you can divide both numbers by). In this case, that number is 5, because you can divide both 5 and 10 evenly by it. Once you divide both numbers by the GCF, your result will be 1/2.
What is the largest number which can divide evenly into both 54 and 45?
9 54/9 = 6 45/9 = 5
