Wendy and Alison swim two days in a row. On day one, Wendy swims 4/6 of a km and on day two she swims 7/10 of km. Alison swims 2/3 of a km and on day two she swims 7/9 of a km. Explain in words how you know which girl swam farther.
I noticed that Wendy and Alison swam the same amount the first day, because 4/6 and 2/3 are equivalent fractions. Then I looked at day two, and so that it proves Alison swam further, because 7/9 is 2 pieces away from being a whole, but 7/10 is three pieces away from being a whole, and I know that ninths is a larger unit that tenths.
