1. The problem asks to explain the number 1.10 further. 2. In decimal notation, 1.10 means one whole unit plus ten hundredths. 3. This can be expressed as the sum: $$1 + 0.10 = 1 + \frac{10}{100}$$ 4. Simplify the fraction: $$\frac{10}{100} = \frac{1}{10}$$ 5. So, 1.10 is equivalent to $$1 + \frac{1}{10} = 1.1$$ 6. Both 1.10 and 1.1 represent the same value; the trailing zero after the decimal does not change the number's value. 7. This is important in understanding decimal place value and precision.
