1 <p>This is a straightforward question on decimal conversion. Firstly, we need to understand fractions and decimals. A fraction represents a part of a whole. It consists of two parts: the numerator (the number on top), which represents how many parts of the whole we have, and the denominator (the number below), which shows how many parts make up the whole. In this case, the numerator is 7, and the denominator is 8. A decimal is a way to represent numbers that are 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, and those to the right represent the fractional part.</p>
