What is a reciprocal in math fractions?
A reciprocal is when you take the second fraction in a division problem and flip it Then change the sign to multiply. THIS ONLY WORKS WHEN YOU ARE DIVIDING FRACTIONS!
What is an algorithm for dividing fractions?
keep change flip - which means keep the first # - chage the division sign to multiplication- The reciprocal means flip the 2 # ex.7/2-2/7.
HOW TO DIVide fractions?
first, change the division sign to a muliplication sign. then change the second number in the problem-change the numerator to the denominator and the denominator to the numerator. then multiply the top numbers and bottom numbers like regular multiplication.
What is 6 over 7 divided by 12 over 5?
Whenever you divide fractions, you're supposed to multiply by the reciprocal. So, in this case, you make the division sign a multiplication sign and change the 12/5 to 5/12. The question would then by 6/7 times 5/12. The answer is 5/14.
What property allows the grouping of numbers in parentheses to change without changing the answer?
That would be the associative property. The associative property applies to addition and multiplication, but not to subtraction or division.
How is the multiplication of fractions and division of fractioms alike and different?
Division is the multiplication by the reciprocal or multiplicative inverse. In simpler language, to divide by a fraction change the division sign to multiplication and flip the fraction.

What is the difference between multiplication and division fractions?
In dividing fractions you have to change division to multiplication and change the second fraction into a recipracol(flip the fraction.

Why do they change the division sign to multiplication and change the divisor to its reciprocal?
Well, honey, when you change the division sign to multiplication and the divisor to its reciprocal, you're basically just using a fancy trick to solve the problem more efficiently. It's like putting on your big girl math pants and showing that division who's boss. So, next time you see that division sign, just remember to flip that divisor and multiply like the math wizard you are.
How do you divide fractions to solve for the unkown?
when you divide fractions you need to flip the second fraction to get the reciprocal eg. 4 over 5 would be 5 over 4 then after you flip the second fraction you change the division sign into a multiplication sign and you multiply.
HOW TO USE KCF IN MATHS?
You use KFC in maths to divide fractions. Firstly, you keep the first fraction. Secondly, you flip the second fraction. The result of doing this is a reciprocal. Thirdly, you change the division sign to multiplication. Then you can easily multiply the two new fractions.
Why change mixed numbers to improper fractions?
For addition, subtraction, division and multiplication with other fractions
What happens to the product when you change the grouping of three factors in a multiplication problem?
Nothing. Multiplication is commutative and associative.Nothing. Multiplication is commutative and associative.Nothing. Multiplication is commutative and associative.Nothing. Multiplication is commutative and associative.
Does the inequality sign change when both sides are multipled or divided when using fractions Why or why not?
Not if the fraction is positive. But yes if the fraction is negative. Study the rules of multiplication and division by integers, and you wil see why. Multiplication by a fraction is simplty multiplication by one integer followed by division by another (or the other way round).
How could you change the Exersice 5 so that your rule uses the inverse operation?
You could change it into a multiplication problem
