We can use the distributive property to claim that:

a ⋅ (1 / c) + b ⋅ (1 / c) = (a + b) ⋅ (1 / c)

Then we can reach the conclusion by simplifying this equation using the following property:

a ⋅ (1 / b) = a / b

Quiz (1 point)

• (a ⋅ c) + (b ⋅ c) = (a + b) ⋅ c
• a / b = a ⋅ (1 / b)
• a / b = a ⋅ (1 / b)
• a ⋅ (1 / b) = a / b

• if the following are true:

  • a = x
  • b = y

  then x + y = a + b

• if the following are true:

  • a = b
  • a = c
  • b = d

  then c = d

Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
