Question

0.01 & 0.02 scientific notation difference​

Answer 1

Answer:

Knowing that numbers work differently to the right of the decimal point than they do to the left of the decimal point will help you compare your decimal numbers. You know that 20 is bigger than 10. If you saw the decimal numbers 0.01 and 0.02, which one would you think is bigger? The 0.02 is bigger because we are comparing the digits in the same location. Both the 1 and the 2 are two spaces to the right of the decimal point. Because they both have one zero in front of them, we need to compare the digits themselves.

But if we were comparing 0.01 and 0.002, we wouldn't need to compare the digits because they are in different locations. One number has more zeroes in front than the other. This tells you that the number with more zeroes in front is smaller. So, 0.01 is bigger than 0.002. Now you try comparing 0.34 and 2.12. Which one is bigger and which is smaller? For this one, you see that to the left of the decimal number, one is 0 and the other 2. Just from this information alone, you already know which number is larger and which is smaller. The 2.12 is bigger and the 0.34 is smaller.

Explanation:

Zeros to the left of the first nonzero digits in a number are not significant; they merely indicate the position of the decimal point—
