Which number has a 3 with a value 1/10 the value of the 3 in 3.01

Answers

it will be 3 in 3.01 because it is rounded?????

Final answer:

The number that has a 3 with a value of 1/10 the value of the 3 in 3.01 is 0.3.

Explanation:

The number being asked for is one where the 3 is positioned one decimal place further to the right than it is in the number 3.01, making its value 1/10 the value of the 3 in 3.01. This is interpreted to mean the 3 is place in the tenths position, rather than in the ones position as it is in 3.01. So, the number is 0.3.

To understand why, consider that in the number 3.01, the 3 is in the ones place. Hence it has a value of 3 * 1 = 3. However, in the number 0.3, the 3 is in the tenths place, which gives it a value of 3 * 0.1 = 0.3, which is 1/10 the value of 3.
