    \[a=\frac{ 1 }{ 6 }\] \[b=\frac{ 1 }{ 7}\] \[c=\frac{ 7 }{ 6}\] \[d=\frac{ 6 }{ 7 }\]

    Ok, well, let's think about the idea before we work with the numbers. What operation do we need to do to get cups/serving?

    I would first convert the mixed number to a improper fraction or decimal.

    Multiply the base by the whole number and add to the numerator.

    Very close. Notice that c/d become d/c when it changes to multiplication.
