What is 16/48 + 4/11?

What is 16/48 + 4/11?

This is how you add

16
48
+
4
11

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 16 by 11, and get 176, then we multiply 48 by 11 and get 528.

16/48 times 11

Now for the second term. You multiply 4 by 48, and get 192, then multiply 48 by 11 and get 528.

4/11 times 48

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

176
528
+
192
528

Step 2

Since our denominators match, we can add the numerators.

176 + 192 = 368

That gives us the sum, which is

368
528

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:

368
528
÷ 2 =
184
264

Now, try the same number again.

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

184
264
÷ 2 =
92
132

Now, try the same number again.

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

92
132
÷ 2 =
46
66

Now, try the same number again.

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

46
66
÷ 2 =
23
33

Now, try the same number again.

Nope. Try the next prime number, 3...

Nope. Try the next prime number, 5...

Nope. Try the next prime number, 7...

Nope. Try the next prime number, 11...

Nope. Try the next prime number, 13...

Nope. Try the next prime number, 17...

Nope. Try the next prime number, 19...

Nope. Try the next prime number, 23...

Nope. Try the next prime number, 29...

No good. 29 is larger than 23. So we're done reducing.

Congratulations! Here's your final answer to 16/48 + 4/11
