What is 10/6 + 3/4?

What is 10/6 + 3/4?

This is how you add

10
6
+
3
4

Step 1

Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.

So, we multiply 10 by 4, and get 40, then we multiply 6 by 4 and get 24.

10/6 times 4

Now for the second term. You multiply 3 by 6, and get 18, then multiply 6 by 4 and get 24.

3/4 times 6

We now have a new problem, that looks like this:

40
24
+
18
24

Step 2

Since our denominators match, we can add the numerators.

40 + 18 = 58

That gives us the sum, which is

58
24

Step 3

Now, do we need to simplify this fraction?

First, we attempt to divide it by 2...

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

58
24
÷ 2 =
29
12

So far so good... let's try to divide by that number again.

No good. So next you try the next prime number, which is 3...

No good. So next you try the next prime number, which is 5...

No good. So next you try the next prime number, which is 7...

No good. So next you try the next prime number, which is 11...

No good. So next you try the next prime number, which is 13...

No good. 13 is larger than 12. So we're done reducing.

And we're done! Here's the final answer to 10/6 + 3/4

10
6
+
3
4
=
29
12
