You have to get common denominators. Try 21. Then subtract.
Tina completed 2/3 of her math homework before dinner .George completed 4/7 of his homework before dinner.who completed a greater fraction of homework?
F56
Ricky finished her homework in 5/12 hour and Bob finished his homework in ¾
hr. Who took longer time and how much longer?
To determine who completed a greater fraction of homework, we need to compare the fractions completed by Tina and George.
Tina completed 2/3 of her homework.
George completed 4/7 of his homework.
To compare these fractions, we need to find a common denominator. In this case, the least common denominator (LCD) is 21, which is the least common multiple of 3 and 7.
To express 2/3 with the denominator of 21, we need to multiply both the numerator and denominator by 7: (2/3) * (7/7) = 14/21.
To express 4/7 with the denominator of 21, we need to multiply both the numerator and denominator by 3: (4/7) * (3/3) = 12/21.
Now we can compare the fractions. 14/21 is greater than 12/21.
Therefore, Tina completed a greater fraction of homework.
