Question

explain closer property for rational numbers with 10 examples​

Answer 1

Answer:

closure property

For two rational numbers say x and y the results of addition, subtraction and multiplication operations give a rational number. We can say that rational numbers are closed under addition, subtraction and multiplication. For example: (7/6)+(2/5) = 47/30.

Answer 2

Answer:

Rational numbers are the numbers which can be represented in the form of p/q, where q is not equal to zero.

Take any two rational numbers say 'a' and 'b', if we add, subtract and multiply these two rational numbers,the answer will be another rational number.

Examples:

1. 7/6 + 2/5 = 47/30
2. 5/6 - 1/3 = 1/2
3. 2/5 × 3/7 = 6/35
4. 1/2 + 3/4 = 5/4
5. 1/2 - 3/4 = -1/4
6. 1/2 × 3/4 = 3/7
7. 2/6 × 1/3 = 2/18
8. 1/2 + 2/3 = 7/6
9. 4/2 - 1/3 = 10/6
10. 9/4 × 7/5 = 63/20
