Question

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.

Answer 1

Malik's current quiz grade average can be found by subtracting the decrease in his average from his initial average.

Step-by-step explanation:

To find Malik's current quiz grade average, we need to subtract the decrease in his average from his initial average. Malik's average is 412 points and it decreases by 34 points, so the subtraction expression would be 412 - 34. Evaluating this expression gives us the current quiz grade average.

Subtracting 34 from 412, we get 378. So, Malik's current quiz grade average is 378 points.

Answer 2

Answer: Required expression= 412-34

Current quiz grade average = 378

Step-by-step explanation:

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)

i.e. Current quiz average =412-34 [ i.e. Required expression= 412-34]

i.e. Current quiz average =378

Hence, his current quiz grade average = 378
