Advice

On Monday, {name1} bought a chocolate bar and ate one {frac1name} of it.

We need to subtract this fraction from one whole to find the fraction remaining.

1 - $\frac{1}{\var{frac1denom}}$ = $\frac {\var{monleftfracnum}} {\var{monleftfracden}}$

On Tuesday, {name1} ate one {frac2name} of the fraction remaining.

We need to find one {frac2name} of $\frac {\var{monleftfracnum}} {\var{monleftfracden}}$ .

$\frac{1}{\var{frac2denom}}$ x $\frac {\var{monleftfracnum}} {\var{monleftfracden}}$ = $\frac {\var{monleftfracnum}} {\var{frac2denom*monleftfracden}}$

This fraction cannot be simplified.

So {name1} ate $\frac {\var{monleftfracnum}} {\var{frac2denom*monleftfracden}}$ of the chocolate bar on Tuesday.

This fraction needs to be simplified. Divide both numerator and denominator by {gcd(monleftfracnum,frac2denom*monleftfracden)}.

$\frac {\var{monleftfracnum}} {\var{frac2denom*monleftfracden}}$ = $\frac {\var{answernumerator}} {\var{answerdenominator}}$

So {name1} ate $\frac {\var{answernumerator}} {\var{answerdenominator}}$ of the chocolate bar on Tuesday.
