Sum of Two Negative Addends to Represent -20

To represent the number -20 as the sum of two negative addends, we need to consider different scenarios based on the conditions given:

a) Both addends are integers. b) Both addends are decimal fractions. c) One of the addends is a proper fraction.

Let's explore each scenario in detail:

a) Both addends are integers: To represent -20 as the sum of two negative integers, we can choose any two integers whose sum is -20. For example, we can choose -10 and -10: -10 + (-10) = -20

b) Both addends are decimal fractions: To represent -20 as the sum of two negative decimal fractions, we can choose any two decimal fractions whose sum is -20. For example, we can choose -10.5 and -9.5: -10.5 + (-9.5) = -20

c) One of the addends is a proper fraction: To represent -20 as the sum of a negative proper fraction and an integer, we can choose any proper fraction and an integer whose sum is -20. For example, we can choose -20 and 0.5: -20 + (-0.5) = -20

These are just a few examples of how we can represent -20 as the sum of two negative addends. There are many other combinations that would also yield -20.
