What is 60/60 + 4/6?

What is 60/60 + 4/6?

Here's how we add

60
60
+
4
6

Step 1

Our denominators (bottom numbers) don't match, so we can't add yet.

Since 6 is evenly divided by 60, we can multiply just one term to get a common denominator.

Multiply 4 by 10, and get 40, then we multiply 6 by 10 and get 60.

4/6 times 10

The problem now has new fractions to add:

60
60
+
40
60

Step 2

Since our denominators match, we can add the numerators.

60 + 40 = 100

This yields the answer

100
60

Step 3

The last step is to reduce the fraction if we can.

To find out, we try dividing it by 2...

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

100
60
÷ 2 =
50
30

Now, try the same number again.

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

50
30
÷ 2 =
25
15

Now, try the same number again.

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

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

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

25
15
÷ 5 =
5
3

Now, try the same number again.

No good. 5 is larger than 3. So we're done reducing.

Congratulations! Here's your final answer to 60/60 + 4/6
