In class, you gave your students the problem: Which is greater,213or 27{“version”:”1.1″,”math”:”213or 27″}? While you’re walking around the class checking on their progress, you approach Jasmine. You ask her for the answer. She says that 27{“version”:”1.1″,”math”:”27″}is greater than 213{“version”:”1.1″,”math”:”213″}. She explains that because the numerators are the same, she only has to compare the denominators. Because 7 is smaller than 13, that means the parts are larger, so 27{“version”:”1.1″,”math”:”27″} is larger. Is her reasoning valid? Why or why not?
