1 <p>It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A mixed number combines a whole number and a fraction. Here, 9 is the whole number, and 3/16 is the fraction part. A fraction represents a part from the whole. The numerator (number on the top) here, 3, indicates how many parts out of the whole. The denominator (number below), 16, shows how many parts make the whole. A decimal is a way to represent numbers that are not whole, using a (.) 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>
