Example Question #3 : Additive Inverse Property
Which of the following statements demonstrates the inverse property of addition?
None of the examples in the other responses demonstrates the inverse property of addition.
The inverse property of addition states that for every real number, a number exists, called the additive inverse, such that the number and its inverse have sum 0. Of the statements given, only
demonstrates this property, so it is the correct choice.
Example Question #201 : Fractions
Which of the following statements demonstrates the identity property of addition?
None of the examples in the other responses demonstrates the identity property of addition.
The identity property of addition states that there is a number 0, called the additive identity, that can be added to any number to yield that number as the sum. Of the four statements,
demonstrates this property.
Example Question #202 : Fractions
Which of the following is the sum of two-thirds and one-fifth?
Since , rewrite each fraction as its equivalent in fifteenths and add the numerators:
Example Question #1 : Decimals With Fractions
Find the sum of the following:
To get the decimal from a fraction, divide the numerator by the denominator
Example Question #493 : Arithmetic
Solve:
The numerators of a fraction cannot be added or subtracted if their denominators are different.
Find the least common denominator, or LCD, by multiplying the denominators together.
Both fractions share the common denominator 28. The numerator must multiply with what was multiplied by their denominator to get the LCD. Rewrite the fractions.
Subtract the numerators. Remember, the denominator does not change when we add or subtract fractions.
Example Question #492 : Concepts
Simplify:
The denominators must be like before the numerators can be subtracted.
Find the least common denominator, which is 12.
Remember, when creating common denominators you must multiply the numerator by the same number that you multiplied the denominator by to get the common denominator.
and
Example Question #203 : Fractions
Add:
Since the denominator is alike, combine the numerators. Do not add the denominators.
Example Question #204 : Fractions
Add:
The denominators of the fractions are alike. This means we can add the numerators. The denominator will stay the same.
Example Question #205 : Fractions
Subtract:
First, find the common denominator. The common denominator is four.
Rewrite the fractions.
Example Question #495 : Concepts
Evaluate:
Find the common denominator. The common denominator is since goes into three times.
Rewrite the fraction.
