Banana Sales Area
1. **Problem 1: Bananas sold by Millie**
Millie had 600 bananas. She sold \(\frac{1}{5}\) of them on Saturday and \(\frac{3}{8}\) of the remaining bananas on Sunday.
**a) How many bananas did she sell on Saturday?**
Calculate \(\frac{1}{5}\) of 600:
$$\frac{1}{5} \times 600 = \frac{1}{5} \times \frac{600}{1} = \frac{600}{5} = 120$$
So, she sold 120 bananas on Saturday.
**b) How many bananas did she sell on Sunday?**
First, find the remaining bananas after Saturday:
$$600 - 120 = 480$$
Now, calculate \(\frac{3}{8}\) of 480:
$$\frac{3}{8} \times 480 = \frac{3}{8} \times \frac{480}{1} = \frac{1440}{8} = 180$$
So, she sold 180 bananas on Sunday.
**c) How many bananas did she sell on both days?**
Add the bananas sold on Saturday and Sunday:
$$120 + 180 = 300$$
So, she sold 300 bananas in total.
**d) How many bananas does she have now?**
Subtract the total sold from the original amount:
$$600 - 300 = 300$$
She has 300 bananas left.

2. **Problem 2: Luas lahan pertanian Paman (Area of Paman's farm)**
Paman has a rectangular farm with width \(5 \frac{3}{5}\) hm and length \(3 \frac{3}{4}\) hm.
Convert mixed numbers to improper fractions:
Width:
$$5 \frac{3}{5} = \frac{5 \times 5 + 3}{5} = \frac{25 + 3}{5} = \frac{28}{5}$$
Length:
$$3 \frac{3}{4} = \frac{3 \times 4 + 3}{4} = \frac{12 + 3}{4} = \frac{15}{4}$$
Calculate the area of the rectangle:
$$\text{Area} = \text{width} \times \text{length} = \frac{28}{5} \times \frac{15}{4} = \frac{28 \times 15}{5 \times 4} = \frac{420}{20} = 21$$
So, the area of Paman's farm is 21 hm\(^2\).
