Together, Shaquille Oatmeal and Jarrod the Rap God have 101 2/8 blue bananas. If Shaquille Oatmeal has 27 1/4 fewer bananas than Jarrod the Rap God, how many blue bananas does Jarrod have? Which algebraic equation best matches the scenario?

• 101 2/8 = J - 27 1/4

• 24 1/4 - J =

  101 2/8

• J - 27 1/4 =

  101 2/8

• 101 2/8 + 27 1/4 = j
