Are you looking to work out and calculate how to subtract 17/82 from 17/89? In this really simple guide, we'll teach you exactly what 17/82 - 17/89 is and walk you through the step-by-process of how to subtract one fraction from another.
To start with, the number above the line in a fraction is called a numerator and the number below the line is called the denominator.
Why do you need to know this? Well, because to subtract a fractions from another we need to first make sure both fractions have the same denominator.
Let's set up 17/82 and 17/89 side by side so they are easier to see:
17
82
-
17
89
Our denominators are 82 and 89. What we need to do is find the lowest common denominator of the two numbers, which is 7298 in this case.
If we multiply the first denominator (82) by 89 we will get 7298. If we we multiply the second denominator (89) by 82 we will also get 7298. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:
17 x 89
82 x 89
-
17 x 82
89 x 82
This is what 17/82 minus 17/89 looks like with the same denominator:
1513
7298
-
1394
7298
Now that these fractions have been converted to have the same denominator, we can subtract one numerator from the other to make one fraction:
1513 - 1394
7298
=
119
7298
You're done! You now know exactly how to calculate 17/82 - 17/89. Hopefully you understood the process and can use the same techniques to add other fractions together. The complete answer is below (simplified to the lowest form):
119/7298
