To solve this problem, we need to determine how many weeks it will take for the plant to grow 7 4/5 inches.
First, we need to convert the mixed number 7 4/5 into an improper fraction.
7 4/5 = (7 * 5 + 4)/5 = 39/5
Next, we can set up a proportion to find the number of weeks it will take for the plant to grow 39/5 inches.
1 2/5 inches/week = 39/5 inches/x weeks
Now, we can cross multiply and solve for x:
(1 2/5) * x = (39/5)
To simplify, we can convert the mixed number 1 2/5 into an improper fraction:
(7/5) * x = 39/5
To isolate x, we can multiply both sides of the equation by the reciprocal of 7/5, which is 5/7:
(7/5) * (5/7) * x = (39/5) * (5/7)
This simplifies to:
x = 39/7
Therefore, it will take the plant approximately 39/7 weeks to grow 7 4/5 inches.
