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
