Here we will show you step-by-step how to simplify 63/21 to the simplest form.
The key to solving this problem is to find the greatest common divisor of 63 and 21.
To find the greatest common divisor of 63 and 21, we list all of the factors of both numbers so we can compare the lists.
When we compared the factors of 63 (1, 3, 7, 9, 21, 63) and 21 (1, 3, 7, 21) we found that 21 is the largest factor that they have in common.
Since 21 is the largest common factor of 63 and 21, 21 is also the greatest common divisor of 63 and 21.
Now, we divide both the numerator and denominator in 63/21 by the greatest common divisor as follows:
Numerator: 63/21 = 3
Denominator: 21/21 = 1
Then, we put the numerator and denominator that we are left with back together to get 3/1.
3/1 is an improper fraction, which means we have to simplify further.
3 divided by 1 is 3, so the answer is:
3
The answer here happened to be a whole number, so you also could have simply divided 63 by 21 to get the same answer.
