DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "contextFraction.pl", "AnswerFormatHelp.pl", ); TEXT(beginproblem()); |
Initialization: |
Context("Fraction-NoDecimals"); $answer = Compute("3/2"); |
Setup:
The macro Context("Fraction"); Context("Fraction-NoDecimals"); Context("LimitedFraction"); Context("LimitedProperFraction"); For the differences among these, see the POD documentation contextFraction.pl.html |
Context()->texStrings; BEGIN_TEXT Simplify \( \displaystyle \frac{6}{4} \). $BR $BR Answer = \{ ans_rule(20) \} \{ AnswerFormatHelp("fractions") \} END_TEXT Context()->normalStrings; |
Main Text: |
$showPartialCorrectAnswers = 1; ANS( $answer->cmp( studentsMustReduceFractions=>1, reduceFractions=>1, allowMixedNumbers=>0, ) ); |
Answer Evaluation: There are many context flags that control how fraction answers are checked. See the POD documentation contextFraction.pl.html |
Context()->texStrings; BEGIN_SOLUTION ${PAR}SOLUTION:${PAR} Factor and cancel to obtain \( \displaystyle $answer \) END_SOLUTION Context()->normalStrings; ENDDOCUMENT(); |
