Answer:
60 D's
Step-by-step explanation:
We are given that the ratio of D to A is 4 to 72,
We can write that as 4:72.
Since students got 1080 A's. we can divide 1080 by 72 to help us find the answer.
1080/72=15
We know that the relationship between the amount of D's simplified and the actual amount of D's is equal to 15 times. So we do the given amount (4) multiplied by 15 (4*15) to get 60.
