Answer:
1/6 is the answer and in decimal form if you need it that way is 0.16
How To get the answer step by step:
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 8 by 8, and get 64.
Then we multiply 4 by 12, and get 48.
Next we give both terms new denominators -- 12 × 8 = 96.
So now our fractions look like this:
64/96 − 48/96
Since our denominators match, we can subtract the numerators.
64 − 48 = 16
So the answer is:
16/96
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...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
16/96÷ 2 = 8/48
Let's try dividing by 2 again...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
8/48÷ 2 =4/24
Let's try dividing by 2 again...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
4/24÷ 2 =2/12
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
2/12÷ 2 =1/6
2 is larger than 1. So we're done reducing.
There you have it! The final answer is:
8/12−4/8=1/6
