Select the postulate that is illustrated for the real numbers.
3 + 2 = 2 + 3
1. the commutative postulate for multiplication
2. multiplication identity
3. the addition inverse postulate
4. commutative postulate for addition
5. the distributive postulate
6. the addition of zero postulate
7. the multiplication inverse

4. Commutative postulate for addition

Step-by-step explanation:

The commutative postulate for addition says that for any real number a and b

a+b=b+a

It tells that order doesn't matter if we add two numbers , the answer will remain same

The given expression is , where 3 and 2 are real numbers.

Since

Therefore, by Commutative postulate for addition.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
