What is 60/60 + 4/5?

What is 60/60 + 4/5?

This is how we add

60
60
+
4
5

Step 1

Now we need to make our denominators match.

60 goes into 5 evenly, so we only need to multiply one term to get a common denominator.

Multiply 4 by 12, and get 48, then we multiply 5 by 12 and get 60.

4/5 times 12

This gives us a new problem that looks like so:

60
60
+
48
60

Step 2

Since our denominators match, we can add the numerators.

60 + 48 = 108

That gives us an answer of

108
60

Step 3

Can this fraction be reduced?

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

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

108
60
÷ 2 =
54
30

Let's try dividing by that again...

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

54
30
÷ 2 =
27
15

Let's try dividing by that again...

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:

27
15
÷ 3 =
9
5

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...

No good. 7 is larger than 5. So we're done reducing.

There you have it! Here's the final answer to 60/60 + 4/5

60
60
+
4
