Answer:
1 3/4
Step-by-step explanation:
you have to convert the mixed numbers into improper fractions first
2 1/2 turns into 5/2
then you make the denominators the same
5/2 turn into 10/4
then you subtract
10/4 - 3/4 = 7/4
then you turn it into a mixed number
7/4 turns into 1 3/4
Solve this by dividing the 180 by 6. This results in 30. So, each number should be rolled 30 times. There are only two numbers greater than 4. Multiply 30 by 2 to get your answer, 60.
