demonstrates this property, so it is the correct choice.

Example Question #415 : Operations And Properties

Which of the following statements demonstrates the identity property of addition?

Possible Answers:

None of the examples in the other responses demonstrates the identity property of addition.

Correct answer:

Explanation:

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 #193 : Fractions

Add the fractions below:

 

Possible Answers:

Correct answer:

Explanation:

To add fractions with different denominators, first the fractions should be rewritten as equivalent fractions with the same denominators. The simplest common denominator to get is the product of the denominators (i.e. , in this question). However, the best denominator to use is the least common denominator, which is the least common multiple of the denominators (which is 12 in this case).

 

 

Now the denominators are equal and we can add the numerators:

 

 

which can be written as:
