You can put this solution on YOUR website!
1/A=1/M+1/T
1/A-1/M=1/T
(M-A)/AM=1/T CROSS MULTIPLY
T(M-A)=AM DIVIDE BOTH SIDES BY (M-A)
T=AM/(M-A)

1%2FA+=+1%2FM+%2B+1%2FT
multiply both sides by AMT
MT+=+AT+%2B+AM
MT+-+AT+=+AM
T%28M+-+A%29+=+AM
T+=+AM+%2F+%28M+-+A%29
This can also be expressed as
T+=+1+%2F+%28%281%2FA%29+-+%281%2FM%29%29
