How is multiplying and dividing integers the same as multiplying and dividing rational numbers?

How is multiplying and dividing integers the same as multiplying and dividing rational numbers?

In this lesson, you will learn the rules for dividing all integers and rational numbers. Thankfully, the sign rules are the same to that of multiplication. A rational number is the result of dividing two integers. If the signs of the divisor and dividend are the same, then the quotient will be positive.

How is multiplying and dividing rational numbers similar?

Remember that dividing rational numbers is the same as multiplying by the reciprocal of the divisor, so that 4/5 ÷2/3 is the same as 4/5 ·3/2, so that 4·3 equals 12 and 5·2 equals 10. Since 2 is a common factor in both the numerator and denominator, the fraction in simplest terms is 6/5.

Are the rules for multiplying and dividing integers the same?

When you divide a positive number by a negative number then the quotient is also negative. When you divide two negative numbers then the quotient is positive. The same rules hold true for multiplication.

Why are the rules for multiplying and dividing rational numbers the same?

Multiplying & Dividing Rational Numbers We follow the same rules as we would if we were multiplying or dividing integers. If your signs are the same, your answer is positive. If your signs are different, your answer is negative.

What is the rule for dividing rational numbers?

To divide two numerical fractions, we multiply the dividend (the first fraction) by the reciprocal of the divisor (the second fraction). For example: We can also use this method to divide rational expressions.

How do you multiply numbers for dummies?

Multiply larger numbers When multiplying by larger numbers with two digits or more, use one placeholding zero when multiplying by the tens digit, two placeholding zeros when multiplying the hundreds digit, three zeros when multiplying by the thousands digit, and so forth. So 53 47 = 2,491.
