Answer: The greatest number of rows Li Na can plant is 9.
Step-by-step explanation:
Given: Li Na is going to plant 63 tomato plants and 81 rhubarb plants.
Li Na would like to plant the plants in rows where each row has the same number of tomato plants and each row has the same number of rhubarb plants.
To find the greatest number of rows Li Na can plant, we need to find the GCF of 63 and 81.
Since , ![63=7\times9\ and\ 81=8\times9](https://tex.z-dn.net/?f=63%3D7%5Ctimes9%5C%20and%5C%2081%3D8%5Ctimes9)
Clearly, GCF(63,81)=9
Therefore, the greatest number of rows Li Na can plant is 9.
Answer:y=1/2
Step-by-step explanation:
Make an equation.
.1 X .5 X n = .25 X n - 30
.05n = .25n - 30
30 = .20n
150 = n
