Answer:
18
Explanation:
If elephant grass grows 3 3/5 inches per day, we can calculate the total growth in 5 days by multiplying the daily growth rate by the number of days.
Daily growth rate: 3 3/5 inches
Number of days: 5
To calculate the total growth, we can convert the mixed number 3 3/5 to an improper fraction:
3 3/5 = (5 * 3 + 3) / 5 = 18/5
Now we can calculate the total growth:
Total growth = Daily growth rate * Number of days
= (18/5) inches * 5 days
= 18 inches
Therefore, the elephant grass will grow 18 inches in 5 days.
