Answer:
1. 1/5 1/3 4/6
2. 3/5 3/4 7/8
3. 87 nickels
4. 150 minutes
5. 2
6. 3/4
Explanation:
1. least to greatest: 1/5 1/3 4/6
2. least to greatest: 3/5 3/4 7/8
3. 1 nickel = 5 cents
So 485 ÷ 5 = 87 nickels
4. Total number of minutes = 50 x 2 = 150 minutes
5. A composite number is a whole number that can be made by multiplying other whole numbers.
3 x 3 = 9 ⇒ composite number
3 x 5 = 15 ⇒ composite number
3 x 7 = 21 ⇒ composite number
Therefore 2 is NOT a composite number (it is a prime number)
6. 6/8 = 3/4
