Final answer:
To place the numbers on a number line, calculate the square roots of each number and plot them accordingly.
Step-by-step explanation:
To place the numbers on a number line, we need to find their approximate values. Let's calculate the square roots of q, r, s, and t:
q = √157 ≈ 12.53
r = √75 ≈ 8.66
s = √51 ≈ 7.14
t = √223 ≈ 14.93
Now let's plot these values on a number line:
q = 12.53 →
r = 8.66 →
s = 7.14 →
t = 14.93 →
