1 <p>It is a simple question on decimal conversion. Firstly, we have to learn mixed numbers, fractions, and decimals. A mixed number consists of a whole number and a fraction. A fraction represents a part of the whole. It has two parts: the numerator (number on the top), here 1 represents how many parts out of the whole, and the denominator (number below) shows how many parts make the whole, here it is 20. A decimal is a way to represent numbers that are not whole, using a (.) or a decimal to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.</p>
