A reciprocal is useful to know in math because to divide fractions, you must multiply by the second fraction's reciprocal. For example:
2/3 divided by 4/7
is the same as
2/3 times 7/4.
A reciprocal is 1 divided by a number. So, the reciprocal of x is 1/x. For example: The reciprocal of 2 is 1/2 is 0.5 The reciprocal of 9 is 1/9 is 0.111111111111 The reciprocal of 0.5 is 1/0.5 is 2. To divide one by a number is called 'taking the reciprocal.' If you have a fraction, taking the reciprocal is fairly easy: simply 'flip' it. I.e., put the numerator in the denominator, and the denominator in the numerator. For example: The reciprocal of 2/3 is 3/2 The reciprocal of 7/8 is 8/7 The reciprocal of 1/4 is 4 (/1). The technical mathematical definition of the reciprocal of x is: "The number which, when multiplied by x, gives one."
Mathematics are useful in everyday life. It can help you do your "math" homework, and do your math test/ exams.
The reciprocal of any non-zero number is one divided by that number. The reciprocal of 0 is not defined. For example, if R(x) represents the reciprocal of x, then R(6) = 1/6 R(5/7) = 1 / (5/7) = 1*(7/5) = 7/5 R(x) = 1/x
Either it is an expression yelled by a teacher when something goes wrong, or it is an alternative term for "to find the reciprocal of". For example, the reciprocal of 3/4 is equal to 4/3 - you have "flipped" the fraction around.
co'z it can be in what ever job math is useful beco'z its can fell ur mind fresh
What does reciprocal mean in fractions
-My teacher likes for us to use math terms, such as reciprocal, in class.
The multiplicative inverSe
1/a is the reciprocal of a
Interest and percent I know. Proportions are useful for finding that.
Flip is the technical term for a reciprocal. (The reciprocal of 3/4 is 4/3)
Math is very useful. You may not realize it but you are always using math. From counting how many eggs to cook or paying for something you'll always need it. I personally don't love math but i know it will be extremely useful in my future.
Math sucks c:
yes, math is useful. But you probably won't need higher then 1st year calc
The reciprocal is the "multiplicative inverse". This means 1 divided by the number. The reciprocal of 2 is 1/2, the reciprocal of 5 is 1/5, etc.
The reciprocal of a number is: 1 divided by the number. Example: the reciprocal of 2 is 1/2 and 5 is 1/5..
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!
