Question
What decimal number does each letter represent in the number line below?
Answer

There are 4 divisions between 6.4 and 6.5, so each division is one-fourth part of 0.1 or \(\frac{1}{10}\), i.e., \(\frac{1}{40}\) = 0.025 unit. Therefore, the second division after 6.4, denoted by ‘a’, represents the number 6.45, while the first division after 6.5, denoted by ‘c’, represents the number 6.525, and the second division after 6.5, denoted by ‘b’, represents the number 6.55.
