Answer:

Dallas studied 3 1/4 hours

Step-by-step explanation:

Find the least common multiple of 2 3 and 4

2: 2 4 6 8 10 12 14 16

3: 3 6 9 12 15 18 21 24

4: 4 8 12 16 20 24 28 32

The least common multiple of 2 3 and 4 is 12

so change the fractions into improper fractions

1 1/2 - 3/2

3/4- 3/4

1 2/3- 5/3

3/2 = 18/12

3/4 = 9/12

5/3 = 20/12

18+9+12 = 39

39/12 simplified is 13/4= 3 1/4
