The algorithm is A/B * C/D = AB/CD.
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
By dividing
It the two rational numbers have different signs, then the answer will be negative, otherwise it will be positive.
It the signs of the two numbers that you are multiplying or dividing is the same, then the answer is positive, otherwise the answer is negative. Remember though, that division by 0 is not defined.
Describe an algorithm for dividing rational numbers.
The algorithm is A/B * C/D = AB/CD.
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
Dividing by a rational number (other than zero) is simply multiplication by its reciprocal.
By dividing
The rules are the same.
It the two rational numbers have different signs, then the answer will be negative, otherwise it will be positive.
Dividing rational numbers involves inverting the divisor and multiplying, which can help simplify calculations. The result of dividing two rational numbers is also a rational number, provided the divisor is not zero. Additionally, the process demonstrates that division can be viewed as multiplication by the reciprocal, maintaining the properties of rational numbers throughout. Overall, understanding this concept is crucial for effectively working with fractions and ratios in mathematics.

A rational number is any number that can be made by dividing one integer by another.0.5 is a rational number as it can be made by dividing the number 1 by the number 22 is a rational number because it can be made by dividing 2 by 1-6.6 is a rational number because it can be made by dividing -66 by 10---------------------------------------------------------Note there are number that are called irrational numbers. Irrational numbers are all "real" numbers (numbers with a decimal point) that cannot be written as a simple fraction - the decimal goes on forever without repeating.For instance the number Pi is an irrational number.A rational number is a real number that can be expressed as a ratio of two integers. Another way to think about it is this: if you can write a number as a fraction then it's a rational number.
To add rational numbers, you can use the algorithm of finding a common denominator. First, identify the least common denominator (LCD) of the fractions involved. Then, convert each fraction to an equivalent fraction with the LCD, add the numerators together, and simplify the resulting fraction if necessary. This process ensures that you accurately combine the rational numbers.
It the signs of the two numbers that you are multiplying or dividing is the same, then the answer is positive, otherwise the answer is negative. Remember though, that division by 0 is not defined.
