Here are the answers to your questions:

Question 1: What is the least common denominator for 6/8 and 5/6?

  • The least common denominator (LCD) for 6/8 and 5/6 is 24.

Question 2: Jose is baking a cake. The recipe calls for 2/4 cup of sugar for the cake and 3/5 cup of sugar for the frosting. How many cups of sugar will he need in all?

  1. First, convert 2/4 to a simpler fraction: 2/4 = 1/2.
  2. Now we need to find a common denominator to add 1/2 and 3/5. The common denominator is 10.
    • Rewrite 1/2 as 5/10 and 3/5 as 6/10.
    • Now add 5/10 + 6/10 = 11/10, which is equal to 1 1/10.
  • Thus, Jose will need 1 1/10 cups of sugar in all.

Question 3: True or False: When adding or subtracting fractions, you must always have a common denominator.

  • The response is True.

Question 4: Find the difference: 3/4 − 2/6.

  1. To subtract these fractions, find a common denominator, which is 12.
    • Rewrite them: 3/4 becomes 9/12 and 2/6 becomes 4/12.
    • Now subtract: 9/12 - 4/12 = 5/12.
  • The answer is 5/12.

Question 5: Find the sum: 4/6 + 2/3.

  1. Convert 2/3 to have a common denominator of 6: 2/3 = 4/6.
  2. Now add: 4/6 + 4/6 = 8/6.
  3. Simplifying 8/6 gives us 4/3, which can be written as 1 1/3.
  • The answer is 1 1/3.
