1. the difference of two natural numbers is always an integer.
2. the difference of two natural numbers is always a natural number.
3. the sum of two natural numbers is always a natural number.
4. the product of two natural numbers is always a natural number.
5. the quotient of two natural numbers is always a rational number
6. the quotient of two natural numbers is always a natural number.
7. the ratio of two natural numbers is always positive

i need determining which ones are true and which are false

1. The difference of two natural numbers is always an integer. True

Like 6-3=3 and 3-6=-3 both 3 and -3 are integers.

2. The difference of two natural numbers is always a natural number. False.

For any two natural numbers a and b, a-b = natural number only when a>b.

Like 5-2=3 is natural but 2-5=-3 is not a natural number.

3. The sum of two natural numbers is always a natural number. True

4. The product of two natural numbers is always a natural number. True

5. The quotient of two natural numbers is always a rational number. True

6. The quotient of two natural numbers is always a natural number. False

7. The ratio of two natural numbers is always positive. True

Natural numbers are 0,1,2,3... all positive numbers, so their ratio will always be positive.
