Let's analyze the problem from the uploaded image.

The image provides a scenario regarding Mr. Tono's land, which covers **2 km²**, and it is estimated that **8 houses** can be built on it. The questions related to this scenario are as follows:

### Questions:
1. Write the ratio of land to the number of houses in its simplest form.
2. How many houses can be built if Mr. Tono has 4 km² of land?
3. If Mr. Tono plans to build 32 houses, how much land is required?
4. State 3 equations from the ratio 10:4.

### Solutions:

a. **Write the ratio of land to houses in its simplest form:**

   - We know that **2 km²** of land can accommodate **8 houses**. So, the ratio of land to houses is:
     \[
     \text{Ratio} = \frac{2 \text{ km}^2}{8 \text{ houses}} = \frac{1}{4}
     \]
     Hence, the simplest form of the ratio of land to houses is **1:4**.

b. **How many houses can be built if Mr. Tono has 4 km² of land?**

   - If 1 km² can fit 4 houses (from the ratio), then **4 km²** will fit:
     \[
     4 \text{ km}^2 \times 4 \text{ houses per km}^2 = 16 \text{ houses}
     \]
     Therefore, **16 houses** can be built on 4 km² of land.

c. **If Mr. Tono plans to build 32 houses, how much land is required?**

   - From the ratio **1:4**, 1 km² can accommodate 4 houses. To build 32 houses, the land required would be:
     \[
     \frac{32 \text{ houses}}{4 \text{ houses per km}^2} = 8 \text{ km}^2
     \]
     So, he would need **8 km²** of land.

d. **State 3 equations from the ratio 10:4:**

   - Some possible equivalent equations based on the ratio 10:4:
     1. \(\frac{10}{4} = \frac{5}{2}\)
     2. \(10x = 4y\)
     3. \(\frac{x}{y} = \frac{10}{4}\)

Let me know if you need further clarifications or details! Here are five related questions you might find useful:

1. If Mr. Tono's land size tripled, how many houses could he build?
2. What is the ratio of houses to land?
3. How much land would be required for 20 houses?
4. If the land area was reduced by half, how many houses could be built?
5. How many houses can be built on 6 km² of land?

**Tip:** When working with ratios, always simplify to the smallest whole numbers for easier calculations.

Pak Tono memiliki lahan seluas 2 km² yang diperkirakan dapat dibangun 8 rumah. Jawablah pertanyaan berikut: 1. Tuliskan rasio lahan dan rumah dalam bentuk yang paling sederhana. 2. Berapa rumah yang dapat dibangun jika Pak Tono memiliki lahan 4 km²? 3. Jika Pak Tono akan membangun 32 rumah maka membutuhkan lahan seluas? 4. Sebutkan 3 persamaan dari rasio 10:4.

Learn how to calculate the ratio of land to houses and solve problems based on Pak Tono's land area of 2 km². Understand how many houses can be built with 4 km² of land and the land required to build 32 houses. Suitable for students in Grades 6-8.
