1 <p>This is a simple question on decimal conversion. Firstly, we need to understand fractions and decimals. A fraction represents a part of a whole. It has two parts: the numerator (the number on top), which indicates how many parts of the whole are being considered, and the denominator (the number below), which shows how many parts make up the whole. Here, the numerator is -1, and the denominator is 8. A decimal is a way to represent a number that is not whole, using a decimal point to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole part, and those to the right represent the fractional part.</p>
