You can put this solution on YOUR website!
if you have:
A=%281%2F2%29w%28b%2Bc%29 for c
A%2F%28w%2F2%29=%28b%2Bc%29
2A%2Fw=b%2Bc
c=2A%2Fw-b


if you have:
A=%281%2F2w%29%28b%2Bc%29 for c
A%2F%281%2F2w%29=%28b%2Bc%29
2wA=b%2Bc
c=2wA-b


if you have:
A=1%2F%282w%28b%2Bc%29%29 for c
2w%28b%2Bc%29=1%2FA
b%2Bc=1%2F2wA
c=1%2F2wA-b
