PG problem file Explanation

Problem tagging data

Problem tagging:

DOCUMENT();

loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"contextFraction.pl",
"AnswerFormatHelp.pl",
);

TEXT(beginproblem());

Initialization:

Context("Fraction-NoDecimals");

$answer = Compute("3/2");

Setup: The macro contextFraction.pl provides four contexts:

Context("Fraction");
Context("Fraction-NoDecimals");
Context("LimitedFraction");
Context("LimitedProperFraction");

For the differences among these, see the POD documentation contextFraction.pl

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


Context()->texStrings;
BEGIN_SOLUTION
${PAR}SOLUTION:${PAR}
Factor and cancel to obtain 
\( \displaystyle $answer \)
END_SOLUTION
Context()->normalStrings;

ENDDOCUMENT();
