Decimals 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 part, and those to the right represent the fractional part. However, in this case, -10 is already a whole number expressed in decimal form.</p>
