Fraction and addition - problem?

7

12

+

8

15

I used the LCD (least common denominator method) and itresulted in,

FLAPJACKS

35

60

and

32

60

I added the nominators together and got

67

60

Now what do I do with this fraction? To make it make senseand be a proper fraction? I tried myself and got

67

127

That was by adding 67 and 60 together then just putting the60 back under.

Re: Fraction and addition - problem?

That is very badly written. If you don't want to use LaTeX, at least write it as 7/12+ 8/15

Yes 67/60 is the correct answer. Whether you write that as 67/60 or "1 and 7/60" depends upon what you want to with it, which you prefer and, perhaps most importantly, **what you teacher wants**.

But when you say "That was by adding 67 and 60 together then just putting the60 back under." I have absolutely no idea **why** you would add the numerator and denominator. There NO arithmetic operation that requires that.

What is LaTex? I was going to use / but I figured it might be confused with division which is quite a stupid idea since I mentioned fractions in the title. Well I have not had a teacher in nearly 4 years, I'm really awful with math but I've pretty much had to start my maths education starting from basics upwards in the past month due to a test to join a job. I should've listened in school but my class was very bad due to us being in the bottom set and all, I guess you would know if you are a retired teacher?

I remember a YouTube video saying something about adding them together, must've of been with a different fraction problem, I can't remember.

It is code.

I've always found it's a lot more time efficient to go by the following expression:

Arithmetic example:

Algebraic example:

Notice, it's more difficult to spot the LCD with algebra.

I don't have a clue what algerbra is really, I've only ever touched on it once or twice and that was years ago. Please give me a rough idea on what it is about? Why is it needed and does it deserve the title of being hard and complicated?

Re: Fraction and addition - problem?

67/60 is correct, but you're left with a improper fraction. It really depends on what the question or teacher wants. In order to change that from a improper fractions you need to divide. 67 divided by 60 is 1, with a remainder of 7. Keep the denominator and you would have 1 7/60.
