Question

Janelle earned 90% on a test and got 63 points. How many total points were possible on the test? Draw a diagram to organize your information before solving the problem. How would I make a diagram?

Answer 1

Answer:

63 / 0.9 = 70

Answer 2

Answer: The total point is 70

Step-by-step explanation:

Let x represent the total point of the test

90% of x = 63

90/100 × x =63

90x / 100 = 63

cross multiply

90x = 6300

Divde bothside by 90

90x / 90 = 6300/90

x = 70

Therefore the total possible mark is 70
