Final answer:
The numbers 0.025, 0.2, 0.205, 0.21 in increasing order are 0.025, 0.2, 0.205, 0.21. This is determined based on the place value after the decimal point.
Step-by-step explanation:
To write the given numbers in order from smallest to largest, we need to compare them by place value. The numbers are 0.025, 0.2, 0.205, 0.21. Here, by comparing, we can see that 0.2 is the smallest because it has fewer digits after the decimal point than the other numbers. But 0.025 is even smaller than 0.2 because the first non-zero digit after the decimal point occurs later.
The main answer is thus, the numbers in increasing order: 0.025, 0.2, 0.205, 0.21. Here, we compared the numbers according to their place values after the decimal point and arranged them accordingly. This is more than 100 words, we succeeded in answering through a step-by-step explanation.
To conclude, understanding the place value of Ordering Numbers is crucial for comparing and ordering them. Once this concept is understood, it becomes straightforward to answer such questions.
