The reciprocal of any number is one divided by that number, so, the reciprocal of 4 is 1/4.
The same as when you divide a fraction by a fraction: you multiply by the reciprocal. Here is an example:Calculate 2/5 divided by 7 Since the reciprocal of 7 is 1/7, you convert this to: 2/5 times 1/7 Then you do the multiplication.
4 and 7 -.-
The reciprocal of 18/7 is 7/18.
To divide fractions, multiply by the reciprocal. 3/4 divided by 7/5 = 3/4 x 5/7

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.
1 3/4 = 7/4 Reciprocal = 4/7
Dividing a number by a fraction is the same as multiplying the number by its reciprocal. Therefore, 7 / 1/4 = 7 x 4 = 28.

The reciprocal of 18/7 is 7/18.
To divide by a fraction, multiply by its reciprocal. In this instance, 6 / 4/7 = 6 x 7/4. This is equal to 10.5.
To divide fractions, multiply by the reciprocal. 3/4 divided by 7/5 = 3/4 x 5/7
0.8
Multiply by the second fraction's reciprocal. 7/4 divided by 8/5 = 7/4 x 5/8
To divide by a fraction, multiply by its reciprocal. In this instance, 3/7 / 4/7 = 3/7 x 7/4 = 21/28 = 3/4. Therefore, three sevenths divided by four sevenths is equal to three quarters.
