How are reciprocals used when dividing fractions?
When dividing fractions, take the reciprocal of the second fraction, and multiply the first fraction by the reciprocal of the second fraction. Example: (a/b)/(c/d)=(a/b)*(d/c)
What math process uses reciprocals?
When you divide fractions you need to multiply by the reciprocal of the divisor. You would also use it anytime the multiplicative inverse is required.
Is the sum of the reciprocals 1?
No, the product of reciprocals is 1.
Perpendicular lines that have slopes which are negative are called?
It took me forever to find this answer, but the answer is "Reciprocals" Good Luck!
How can you tell if two numbers are reciprocals?
If you multiply two reciprocals, their product must be 1.
What can you say about two fractions whose product is 1?
They're reciprocals.
How do you divide fractions without reciprocals?
Using reciprocals, a/b divided by c/d is the same as a/b times d/c. If you multiply this, you get ad/bc.Without thinking about this as reciprocals, you can do this multiplication directly, cross-multiplication so to speak.
What fractions equal 1 whole?
Fractions that multiply to get 1 whole are reciprocals, or multiplicative inverses.
Two fractions whose product is 1 are known as?
Reciprocals. Example (a/b)(b/a)=(ab/ab)=1
What fractions or whole numbers are reciprocals?
The reciprocal of any whole number is one over that number, like 5 and 1/5
How are reciprocals used when dividing fractions?

Would you find the reciprocal of two improper fractions?
If the fraction is already improper, then all that is needed is to make the numerator the denominator and make the denominator the numerator. Using the property of multiplicative reciprocals, any number times its reciprocal must equal 1. With fractions, in multiplication the numerator and denominator between the reciprocals any which way (den. of 1st and num. of 2nd, or den. of 2nd and num. of 1st) can cancel out. 7/16-->16/7 65/8-->8/65

Why do you compare fractions?
To compare any two fractions they first need to be converted to numbers on a similar basis: Convert both to decimals: the smaller decimal is the smaller fraction. Find equivalent fractions with the same denominator: the fraction with the smaller numerator is the smaller number. Find equivalent fractions with the same numerator: the fraction with the larger denominator is the smaller number. I recommend that the last of these is used for integral reciprocals (comparing 1/2, 1/4, 1/7 etc) or by more proficient users.
Is the sum of the reciprocals 1?
No, the product of reciprocals is 1.
Find the sum of the reciprocals of all the whole number factors of 24?
the answer is -9....
What is the product of two numbers that are opposite reciprocals?
I have a feeling that you wrote "opposite reciprocals"where you only needed to write "reciprocals".Their product is ' 1 '.
