Final answer:
The number 10 times as great as 0.02 is calculated by multiplying 0.02 by 10, which equals 0.20.
So option (A) is the correct answer.
Step-by-step explanation:
The number that is 10 times as great as 0.02 is 0.2. To find a number that is 10 times greater,
When you multiply a number by 10, you are essentially scaling it by a factor of 10. In this case, multiplying 0.02 by 10 results in a product of 0.2. This means that 0.2 is 10 times as great as 0.02.
To understand this, consider the relationship between the two numbers. If you have 0.02 of something and you want to find a quantity that is 10 times larger, you multiply 0.02 by 10, yielding 0.2. Mathematically, this is expressed as
0.02
×
10
=
0.2
0.02×10=0.2.
Therefore, option A) 0.2 is the correct answer, representing a number that is 10 times as great as the given value, 0.02. Options B) 0.5, C) 1.0, and D) 2.0 are not correct in this context as they represent different multiples of 0.02.
