    Need help with a calculation

    I'm no good at Maths so half of the categories I do not understand, so I hope this is the correct place. I only got a C at GCSE stander in Maths, and that was about 2/3 years ago lol.

    Anyway, I was wondering if someone could tell me how to figure this out, below I have put figures showing a total number which is spilt into 3.

    Payment 1: 909.15
    Payment 2: 909.15
    Payment 3: 936.70

    Total Amount: 2755.00

    Well basically the "Total Amount" SHOULD be "3385", so how would I work out Payment 1, 2 and 3? As to me it does not look like it is simply 3385 / 2.

    Thank, in advance

    I am confused. Why should the total amount be 3385?

    Sorry I worded that wrong, the total of 2755.00 which is split into 3 should actually be 3385 split into 3. I just can't figure how out I work out how to split 2755 into 3 to get the 3 amounts, as I need to do that with the 3385. :S I don't know how else to explain it.

    try this,


    Payment 1: \frac{909.15}{2755}\times 3385 =\dots
    Payment 2: \frac{909.15}{2755}\times 3385 =\dots
    Payment 3: \frac{936.70}{2755}\times  3385 =\dots

    Alright, I will try and explain it differently.

    2755 split into 3 = 909.15, 909.15 and 936.70
    3385 split into 3 = ???

    Edit:
    That looks correct I think.

    P1: 1117.05
    P2: 1117.05
    P3: 1150.09

    Thanks

    Is what Pickslides posted. He took the fraction per payment and multiplied it by the new total for the new payments.

    909.15 / 2755 = .33
    .33 * 3385 = 1117.05
    Can you finish it?
