Adding Positive and Negative Rational Numbers

Front

What is the sum of a positive rational number and a negative rational number?

Back

The sum can be found by subtracting the absolute value of the negative number from the positive number. If the negative number's absolute value is greater, the result will be negative.

How do you add two rational numbers with different signs?

Back

To add two rational numbers with different signs, subtract the smaller absolute value from the larger absolute value and keep the sign of the number with the larger absolute value.

Front

What is the result of adding two negative rational numbers?

Back

The result is always a negative rational number, as adding two negative values increases the magnitude of negativity.

What is the result of adding two positive rational numbers?

Back

The result is always a positive rational number, as adding two positive values increases the magnitude of positivity.

How do you convert a negative fraction to a positive fraction?

Back

To convert a negative fraction to a positive fraction, simply remove the negative sign from the numerator or denominator.

Front

What is the process for adding fractions with different denominators?

Back

To add fractions with different denominators, find a common denominator, convert each fraction, and then add the numerators.

What is the sum of -4/6 and 1/3?

Back

The sum is -2/6, which can be simplified to -1/3.

Front

What is the significance of the absolute value in addition of rational numbers?

Back

The absolute value helps determine the magnitude of the numbers being added, which is crucial for understanding the result's sign.

What happens when you add a positive number to zero?

Back

The result is the positive number itself, as zero does not affect the value of the positive number.
