subtract: 4/11 - 8/3
Answers
Answer:
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 3 by 11, and get 33.
Then we multiply 4 by 8, and get 32.
Next we give both terms new denominators -- 8 × 11 = 88.
So now our fractions look like this:
33
88
−
32
88

So now our fractions look like this:
33/88− 32/88
Step 2
Since our denominators match, we can subtract the numerators.
33 − 32 = 1
So the answer is:
188
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
No good. 2 is larger than 1. So we're done reducing.
There you have it! The final answer is:
3/8− 4/11
=
188
