What is 100/50 + 1/2?

What is 100/50 + 1/2?

This is how to add

100
50
+
1
2

Step 1

Now we need to make our denominators match.

50 goes into 2 evenly, so we only need to multiply one term to get a common denominator.

Multiply 1 by 25, and get 25, then we multiply 2 by 25 and get 50.

1/2 times 25

This gives us a new problem that looks like so:

100
50
+
25
50

Step 2

Since our denominators match, we can add the numerators.

100 + 25 = 125

That gives us an answer of

125
50

Step 3

Can this fraction be reduced?

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

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

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

Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:

125
50
÷ 5 =
25
10

Let's try dividing by that again...

Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:

25
10
÷ 5 =
5
2

Let's try dividing by that again...

No good. 5 is larger than 2. So we're done reducing.

There you have it! Here's the final answer to 100/50 + 1/2

100
50
+
1
2
=
5
2
