The image contains a mathematical problem written in Indonesian. Here is the translation of the text:

"A worker can paint a house in 10 days. Assuming the worker's speed is constant, how much of the house can be painted in 1 day?"

Solution:

We are given that a worker can paint an entire house in 10 days. To find out how much of the house the worker can paint in 1 day, we can simply divide the whole job by the total number of days:

$\text{Work done in 1 day} = \frac{1 \text{ house}}{10 \text{ days}} = \frac{1}{10} \text{ of the house}$

Thus, the worker can paint $\frac{1}{10}$ of the house in 1 day.

Would you like more details or have any questions?

Here are some additional questions you could explore:

1. How much of the house can the worker paint in 5 days?
2. If two workers work together, how long will it take them to paint the house?
3. If the worker’s speed doubles, how many days will it take to paint the house?
4. How much of the house can be painted in half a day?
5. How long will it take to paint two houses at the same speed?

Tip: Understanding rates can help solve many real-world problems, such as calculating speed, efficiency, or work output over time!
