Malik earns an average of 412 points on his daily quizzes. Near the end of the quarter, his average decreases by 34 points. Write and then evaluate a subtraction expression (in fraction form) to find his current quiz grade average.

Required expression= 412-34

Current quiz grade average = 378

Given: The average points on daily quizzes = 412

The average decreases by 34 points.  (Near the end of the quarter)

Current quiz average = (Average points on daily quizzes) - (Average decreases)
