1. Ten students in Silverton J.H.S. took 9 days to weed the school compound. How long would 15 students take to weed the compound if they worked at the same rate? ​

Answer:

6 days

Step-by-step explanation:

No. of students | No. of days

10                       | 9

15                       | [tex]\frac{10}{15}[/tex] × 9 = 6

Since the number of students and the number of days is inversely proportionate (when one increases by a certain extent, the other decreases by the same extent), we can calculate the number of days by multiplying the number of days by the fraction of the number of students proportionate to the number of days and the number of students you want to find the number of days for.

It would take 6 days.
