A third grade class was given a multiplication quiz. The quiz had 10 problems. Any correctly answered 6 problems, Bobby answered 7 problems correctly, Tom answered 9 problems correctly, and Sue only answered 2 problems correctly.
A. What fraction of the problems did each student get correct on the quiz?
B. ORDER the fraction of problems each student got correct from greatest to least.
6/10;7/10;9/10;2/10
9/10;7/10;6/10;2/10
To find the fraction of problems each student got correct on the quiz, we need to divide the number of problems each student answered correctly by the total number of problems on the quiz.
A.
For a class of 10 problems:
1. Bobby answered 7 problems correctly, so his fraction is 7/10.
2. Tom answered 9 problems correctly, so his fraction is 9/10.
3. Sue answered 2 problems correctly, so her fraction is 2/10 (which can be simplified to 1/5).
B.
To order the fractions from greatest to least, we compare the numerators (the numbers on the top) and, in case of a tie, the denominators (the numbers on the bottom).
From greatest to least:
1. Tom: 9/10
2. Bobby: 7/10
3. Sue: 1/5
