  2. Jeck and Jill are both 1st Year high school students at Chocolate Hills National High School in Bohol but they belong to different sections. Both of them are living in a dormitory and every morning they climb up the hill to fetch a pail of water. One time they make a bet, whoever performs better in the Semestral Examination in Basic Mathematics will be exempt from fetching water for the whole week. On exam day, Jeck got 60 corrrect answers out of a total of 80 items while Jill got 65 out of 90 in Basic Mathematics. Who do you think got the better score, Jeck or Jill? Jeck Jill 1234567891011121314151617181920

  3. Who do you think won the bet and will be exempt from fetching water? Who performed better in the Basic Mathematics Semestral Examination? Put a check mark before the correct answer or write your answer on the space provided below if you think none of the choices below is the correct one. M. Jeck, because she got 65 while Jill only got 60 A. Jill, because 60/80 is greater than 65/90 T. It cannot be determined because the total number of items are different. H. Other __________________________________ __________________________________________ 1234567891011121314151617181920

  4. Lets analyze this… M.Jeck, because she got 65 while Jill only got 60. Why do you think that a better performance should be based on the score? __________________________ ___________________________ T.Its hard to determine because the total number of items are different. How would you change the given in order to find who performed better? ___________________________ ___________________________ A.Jill, because 60/80 is greater than 65/90 Why do you say that 60/80 is greater than 65/90? ___________________________ ___________________________ H.Other __________________________________________________________________________________________________________________________________________________________________ 1234567891011121314151617181920
