Question

On Monday Sarah had homework in 7⁄10 of her classes, Tuesday 3⁄5 , Wednesday 9⁄11 , and Thursday 1⁄2 . Which day did she have the most homework? A. Wednesday B. Thursday C. Tuesday D. Monday

Answer 1

Answer:
Wednesday

Explanation:
To be able to compare the values, we will first need to have a common denominator for all fractions.
Common denominator is 10*11 = 110
For Monday:
Sarah's homework was 7/10 which is equivalent to 77/110
For Tuesday:
Sarah's homework was 3/5 which is equivalent to 66/110 
For Wednesday:
Sarah's homework was 9/11 which is equivalent to 90/110 
For Thursday:
Sarah's homework was 1/2 which is equivalent to 55/110

Now, we will simply be able to compare these values as follows:
90/110 > 77/110 > 66/110 > 55/110
Therefore, the day with the most homework is the one having 90/110  that corresponds to 9/11 of the classes. This day is Wednesday

Hope this helps :)
