To calculate how many acres Ms. Green planted with potatoes, we need to take \( \frac{3}{4} \) of her total farmland, which is 30 acres.
The calculation is as follows:
\[ \text{Acres planted with potatoes} = \frac{3}{4} \times 30 = \frac{3 \times 30}{4} = \frac{90}{4} = 22.5 \text{ acres} \]
Now let's check the options given:
- 60/4 or 1/5 acres. (Not correct)
- 60/4 or 15 acres. (Not correct)
- 334 or 814 acres. (Not correct)
- 33 or 8 1/4 acres. (Not correct)
- 90/120 or 3/4 acres. (Not correct)
- 90 or 3 4 acres. (Not correct)
- 90/4 or 22.2/4 acres. (Not correct)
None of these options correctly represent the acreage that Ms. Green planted with potatoes, which is 22.5 acres or 90/4 acres. However, it appears that option 90/4 is close, but it doesn't seem to be explicitly stated as 22.5 acres. Please confirm if there's an error in the options.
