Answer:
The correct option is B) 0.7
Explanation:
Consider the provided number line.
By observing the provided number line it can be concluded that the value of √10 is approximately 3.16. Where 1 is at tenths place.
Now, consider the number √15.
The number √15 is on the right side of √10 that means the value of √15 must be greater than √10.
By observing the provided number line it can be concluded that the value of √15 is approximately 3.87. Where 8 is at tenths place.
Thus the difference of the in tenths between √10 and √15 is 0.7
Therefore, the correct option is B) 0.7
