If you added 60 and 25 and 15 minutes up, wouldn't that be your answer? Or am I missing something?

anna's got the right idea ^_^

jigglypuff314 · Answer

except the numbers should be in relation to each other
like how 60 is 4 times 15

atsie · Answer

Darn!
I hate it when I thought I was close, and I end up not being so! xD
The link you just gave is making my head spin now. :P

lovelyanna · Answer

I tried making the denominators the same for each fraction, but 25 doesn't work.

lovelyanna · Answer

Is there a different equation I can use?

jigglypuff314 · Answer

wait! You were completely right about the
1/60 + 1/25 + 1/15 = 1/t

that's all you needed ^_^

lovelyanna · Answer

Ok, that's good to know! But how do I find the answer?

lovelyanna · Answer

I need to add all of them up, but I can't do that without the denominators being the same.

jigglypuff314 · Answer

You could try multiplying every term by 60t

lovelyanna · Answer

How do I do that...? :/

jigglypuff314 · Answer

60t / 60  +  60t / 25  +  60t / 15  =  60t / t

lovelyanna · Answer

60t/60 = t, and 60t/25 = 12t/5. Wouldn't that make it even more complicated?

jigglypuff314 · Answer

I think it would make it more managable?
you can multiply again by 5

jigglypuff314 · Answer

if you want to get rid of that one denominator

lovelyanna · Answer

Let me try. :)

lovelyanna · Answer

After simplifying and multiplying by 5, I got 5t + 12t + 25t = 300. Is that right?

jigglypuff314 · Answer

60/15 = 4 right?
then times 5

lovelyanna · Answer

I think I found an easier way. 300 can be the denominator for each fraction, right?

jigglypuff314 · Answer

that's also right :)

lovelyanna · Answer

Awesome! I just got the answer :D
