Question

The values √8 and √14 are plotted on the number line.

What is the approximate difference in tenths between the two values?
0.5
0.9
1.1
2.4

Answer 1

Firstly, you have to count the number of spaces between the two points on the line, which gives you 9. Now, remember that you are counting between tenths on a number line, so you divide 9 by 10 to give you your answer, 0.9.

Answer 2

The correct option is 2.

Explanation:

The values √8 and √14 are plotted on the number line.

From the given number line it is clear that

`√(8)\approx 2.8`

`√(14)\approx 3.7`

We have to find the approximate difference in tenths between the two values √8 and √14.

`√(14)-√(8)\approx 3.7-2.8`

`√(14)-√(8)\approx 0.9`

The approximate difference in tenths between the two values is 0.9.

Therefore the correct option is 2.
