Answer:
score = 63
Step-by-step explanation:
1. To write the proportion take the score of the test over the number of points and set it equal to the percent over 100
score 90
----------- = -----------
70 100
Using cross products
100 * score = 90*70
100 score = 6300
Divide by 100
100/100 * score = 6300/100
score = 63
To solve this question, you would need to find the common denominator among the 2 fractions. In this case it would be
72.
Then multiply numbers to both of the fractions to get to the bottom number in both fractions equaling 72.
40/72 + 27/72 =67/72.
Try to reduce to lowest terms by dividing a common number from both of them if possible.
