Which number is located between 1 and 2 on the number line?

A. π/2
B. π/4
C. sqrt(5)
D. sqrt(10)

Which number is located between 4 and 5 on the number line?
A. 2π
B. sqrt(8)
C. 2 sqrt(5)
D. 5 sqrt(2)

For the first question, the number located between 1 and 2 on the number line is B. π/4. This is because π/4 is approximately 0.785, which is greater than 1 and less than 2.

For the second question, the number located between 4 and 5 on the number line is B. sqrt(8). This is because sqrt(8) is approximately 2.828, which is greater than 4 and less than 5.
