Answer:

B. 1/12

Step-by-step explanation:

What is 5/6 - 3/4?

What is 5/6 - 3/4?

Here's how to subtract 3/4 from 5/6:

5

6

−  

3

4

Step 1

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 5 by 4, and get 20.

Then we multiply 3 by 6, and get 18.

Next we give both terms new denominators -- 6 × 4 = 24.

So now our fractions look like this:

20

24

−  

18

24

Step 2

Since our denominators match, we can subtract the numerators.

20 − 18 = 2

So the answer is:

2

24

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...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

2

24

÷ 2 =  

1

12

Let's try dividing by 2 again...

No good. 2 is larger than 1. So we're done reducing.

There you have it! The final answer is:

5

6

−  

3

4

= 1/12
