What is 5 over 12 plus 5 over 10?

Answer 1

If the question was in an equation form it would look like so...

5/12 + 5/10 = ?

First of all we have to make the denominators the same in order for the numerators to add.

So what can we multiply with the 2 denominators (12 and 10) that would make them equal. We can use the number 60... to be the denominators of 12 and 10.

So we multiply the 12 (or the 5/12) for the denominator to be 60...

5/12 x 5 = 25/60

Let's go to the 2nd fraction.... what multiplies with 10 to make 60... 6!

So multiply the 5/10 with 6....

5/10 x 6 = 30/60

Are the denominators the same? ... 25/60 + 30/60 = ?

They are! So from what we know about adding two fractions together... the denominators remain the same, but we add the two numerator... so the sum of the 2 fraction is 55/60.

We can't just leave it like that... it can be reduced! What number can we divide the numerator and denominator so it is at it's lowest form? We can divide it by 5.... 55/5 = 11 ... 60/5 = 12 .. and TADA!

The answer is 11/12.
