There are 60 office suites in a downtown building. Using the information listed below, how many office suites does Company C service the computers? (How many are left?)

• Company A services the computers at 1/3 of the office suites.

• Company B services the computers at 2/5 of the office suites.

• 1) Find the Fraction

• 2)Find the number of suites

• First Subtract to Find 1

  1- 1/3 - 2/5 = A/B

  ( Remember to get a common Denominator)

  Then for 2) Use the fraction to set up a proportion:

  A/B = ?/60

• First Add to Find 1

  1/3 + 2/5 = A/B

  ( Remember to get a common Denominator)

  Then for 2) Use the fraction to set up a proportion:

  A/B = ?/60

• First Multiply to Find 1

  1/3 x 2/5 = A/B

  Then for 2) Use the fraction to set up a proportion:

  A/B = ?/60

• First Divide to Find 1

  1/3 ÷ 2/5 = A/B

  Then for 2) Use the fraction to set up a proportion:
