Question

What are the decimal numbers represented by points P and Q on the number line given below?

• A. P = 2.7, Q = 7.9
• B. P = 3.7, Q = 8.9
• C. P = 2.9, Q = 7.7
• D. P = 7.7, Q = 2.9

Answer 1

The correct option is C P = 2.9, Q = 7.7

Any two consecutive whole numbers on the given number line are separated by 9 divisions.
The point P is marked at the 9th division after 2.
Hence, P represents 2.9.
The point Q is marked at the 7th division after 7.
Hence, Q represents 7.7.
