Here we will show you step-by-step how to simplify 7/21 to the simplest form.
The key to solving this problem is to find the greatest common divisor of 7 and 21.
To find the greatest common divisor of 7 and 21, we list all of the factors of both numbers so we can compare the lists.
When we compared the factors of 7 (1, 7) and 21 (1, 3, 7, 21) we found that 7 is the largest factor that they have in common.
Since 7 is the largest common factor of 7 and 21, 7 is also the greatest common divisor of 7 and 21.
Now, we divide both the numerator and denominator in 7/21 by the greatest common divisor as follows:
Numerator: 7/7 = 1
Denominator: 21/7 = 3
Then, we put the numerator and denominator that we are left with back together to get our answer.
7/21 to the simplest form is:
1/3
