What is 9/48 + 1/2?

What is 9/48 + 1/2?

Here's how we add

9
48
+
1
2

Step 1

Now we need to make our denominators match.

Since 2 is evenly divided by 48, we can multiply just one term to get a common denominator.

Multiply 1 by 24, and get 24, then we multiply 2 by 24 and get 48.

1/2 times 24

So now our fractions look like this:

9
48
+
24
48

Step 2

Since our denominators match, we can add the numerators.

9 + 24 = 33

Now we have an answer.

33
48

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...

Nope! So now we try the next greatest prime number, 3...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

33
48
÷ 3 =
11
16

Let's try dividing by that again...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

Nope! So now we try the next greatest prime number, 13...

No good. 13 is larger than 11. So we're done reducing.

There you have it! Here's the final answer to 9/48 + 1/2

9
48
+
1
2
=
11
16
