Show work 5⁄12 + 17⁄60.. Im a dummy when it comes to fractions!

Please explain fractions in dummy terms!!

I know if the Denominator doesn't match you would have to find the LCD. And this apply to Adding and Subtracting fractions.

5/12 + 17/60

common denominator is 60
5/12 12x5= 60
17/60= 60

5/12+17/60= 5/60+17/60

Now this is were i get confused.. do i have to multiply how many times 12 went into 60 with the numerator? 12x5=60 5x5=25 so it would be 25/60 + 17/60 = 42/60 then reduce to lowest terms?

Both fractions need to have the same denominator.

In this case, you'd multiply 12 by 5 to give 60 ... but you have to multiply both the top AND the bottom of the fraction by the same number. So we can say ...

5/12 = 25/60

Now the original sum becomes 25/60 + 17/60 = 42/60

Step 2: can we simplify 42/60 ??

Well, 42 = 6 x 7
... and 60 = 6 x 10

So divide top and bottom of 42/60 by 6:

42/60 = 7/10

Here's the whole sum the way your teacher wants to see it :)

5/12 + 17/60
= 25/60 + 17/60
= 42/60
= 7/10

If you find a common denominator you have to multiply the numerator too or your answer will be wrong, so it should be 25/60+17/60 and the answer should be 42/60 which can be reduced. So you got the answer right, but you forgot to multiply the 5/12.

Now this is were i get confused.. do i have to multiply how many times 12 went into 60 with the numerator? 12x5=60 5x5=25 so it would be 25/60 + 17/60 = 42/60 then reduce to lowest terms?
