Step-by-step explanation:
1. Not all rational numbers are whole numbers. Whole numbers can be rational numbers, if expressed in fraction form. For example, 1 can be expressed as 
. A set of rational numbers consists of a set of numbers written as a quotient of two integers, a and b, in the form 
, where b ≠ 0. The reason why b ≠ 0 because division by zero is an undefined mathematical operation.
2. Irrational numbers differ from rational numbers in terms of its representation: while the rational numbers can be expressed as a ratio or in fraction form, irrational numbers <em>cannot</em> be expressed in fraction form.
Irrational numbers are a set of numbers for which its decimal representations is neither <em><u>terminating</u></em>, nor <em><u>repeating</u></em>. A couple examples of irrational numbers are: π and 
, as their decimal representations do not come to an end and doesn't have a block of repeating digits.
3. All real numbers are rational numbers. <u>Real numbers</u> comprise of natural numbers, whole numbers, integers, rational numbers, and irrational numbers.
Step-by-step explanation: Lets estimate first to the nearest whole number.
15.8 kilograms estimated is 16 kg
17.42 kilograms estimated is 17 kg
16.28 kilograms estimated is 16 kg
Now add the estimated values, 16 + 17 + 16 = 49 kg
The estimate gives you the correct answer because it gives you an accurate reasonable amount in this problem.
