Karson and Hayden were taking a test in math. They both checked their progress at different times during the test and continued to work at the same rate. Karson completed 2/3 of the exam in 5/6 of an hour. Hayden completed 1/10 of the exam in 1/8 of an hour. Who completed the entire test first?indecision

Calculate hours per test for each of them...see which is least

 

Kar  5/6 hr  /  2/3 test  = 5/6 * 3/2 = 15/12 = 1 1/4 hr per test  ( 75 minutes)

Hay 1/8 hr  / 1/10 test = 1/8 * 10 =  10/8   = 1 1/4 hr per test  ( 75 minutes)    It is a tie !
