dividend – a number being divided

divisor – a number dividing into another number
quotient – the answer to a division problem
reciprocal – a pair of numbers that equal 1 when multiplied
together

can you give me an example of it ?

Sure! Let's use the numbers 12 and 4 as an example:

The dividend would be 12 because it is the number being divided.
The divisor would be 4 because it is the number dividing into the dividend.
The quotient would be 3 because 12 divided by 4 equals 3.
The reciprocal of 4 would be 1/4 because when 4 is multiplied by 1/4, it equals 1.
