In this video we will simplify (reduce) the fraction 21/5 into its simplest form. The key to simplifying fractions is to find a number that goes into both the numerator and denominator.
The number 1 will divide evenly into both 21 and 5.
We can list all of the factors that divide evenly into 21 and 5. When we do so we see that 1 is the highest common factor for both numbers.
If we divide 21 by 1 we get 21.
If we divide 5 by 1 we get 5.
This means that we can simplify 21/5 to 21/5. The fractions are equivalent. If you check on a calculator you will find that they have the same decimal value. So we haven't changed the quantity, just the way the fraction is expressed.
