What else can I help you with?
Why do you have to multiply or divide both the numerator and the denominator of a fraction to find an equivalent fraction?
It is the basic law of algebra. When you multiply or divide both by the same number you do not change the value, as it is the same as multiplying or dividing by 1.
What the recipracol?
Reciprocal of a number is the value you get when you divide 1 by that number. Also if you multiply a number with its reciprocal you will always get 1.
What happens when you multiply a fraction by 1?
When you multiply a fraction by 1, the value does not change. It is like this for any number.
What fraction has a reciprocal that is 4 times its value?
The fraction is 1/2. (or more generally, +/- one half) Where a ratio is given between the reciprocal and the fraction, the reciprocal (and denominator of the fraction) is the square root of the ratio. 1/x = 4x 1 = 4x2 4x2 = 1 x2 = 1/4 x = 1/2 (or -1/2)
What happens when you multiply both the numerator and denominator of a fraction by 4?
The value of the fraction remains unchanged
How do you find a reciprocal?
A reciprocal is the number you must multiply another number by to get the product of 1. The reciprocal of 4 (which is the same as 4/1) is 1/4. The reciprocal of 3/8 is 8/3. The reciprocal of 13 is 1/13.This can also be expressed using exponents. The reciprocal of any value x is equal to x-1. So the reciprocal of a/b is (a/b)-1, which is equal to b/a.To find a reciprocal, put the number under one. If it is a fraction, flip the fraction. Whatever the reciprocal is, remember that it must always multiply to one with the original number.
What is the reciprocal of three sevenths?
Reciprocal of 3/7 is 7/3, when you multiply a number with its reciprocal you will get the value 1.
Why do you have to multiply or divide both the numerator and the denominator of a fraction to find an equivalent fraction?
It is the basic law of algebra. When you multiply or divide both by the same number you do not change the value, as it is the same as multiplying or dividing by 1.
Why is the quotient larger than the dividend when dividing by a unit fraction?
Rules for dividing by a fraction are multiply by the reciprocal. The reciprocal of a unit fraction is a whole number. Multiplying by a whole number will make the answer (quotient) larger. ex unit fraction 1/a 7 divided by 1/a = 7 x a/1 = 7a .... a times larger than 7.

What is the reciprocal number?
A reciprocal of a number is the value you get by dividing 1 by the number. For example, if you want to find the reciprocal of 10, then you divide 1 by 10 and you get 1/10. You can find the reciprocal of a fraction as well. Thus if you want the reciprocal of 1/10 then you divide 1 by 1/10 which is (1)/(1/10) which yields the original number we started with, namely 10. So 10 and 1/10 are reciprocals of each other. Note also that multiplying any number by its reciprocal will always yield 1.
What is the reciprocal frequency?
The reciprocal frequency is the inverse of the frequency, calculated by dividing 1 by the frequency value. It is commonly used in physics and engineering to describe the time period corresponding to a specific frequency.
What happens when you multiply both the numerator and denominator of a fraction by 4?
The value of the fraction remains unchanged
Which fraction has the same value and look different?
The fraction that you get when you multiply the numerator and denominator of the original fraction both by the same number.
When you multiply a fraction by a number greater than one how does the product compare to the fraction?
The absolute value of the answer will be greater than the absolute value of the original.
