While teaching Class VI students, teacher explains that :
8 + 7=A Whole Number
8 x 7=A Whole Number
7/8 = Is not a Whole Number
Which property he/she explaining this way ?

Correct option is C

The closure property states that for any two numbers in a set, the sum, difference, product, and quotient (if the divisor is not zero) are also in the set. In this case, the teacher is explaining that the sum, product, and difference of two whole numbers are also whole numbers, but the quotient of two whole numbers is not always a whole number.
