Answer 1

Answer:

The answers are as follows:

5. $12+3 = 3+12$

7. $(6+4)+8 = 6+(4+8)$

9. $(10*5)*7 = 10*(5*7)$

Step-by-step explanation:

5. 12 and 3

Commutative property of addition states that the order of two numbers in addition doesn't matter; the result will be the same. If a and b are two numbers then the property will be:

a+b = b+a

For the given question, the commutative property will be:

$12+3 = 3+12$

Associative property deals with three numbers or variables. It states that when 3 numbers are being added or multiplied their order doesn't affect the result.

It can be stated as:

(a+b)+c = a+(b+c)

7. 6,4 and 8

The associative property will be:

$(6+4)+8 = 6+(4+8)$

9. 10,5 and 7

$(10*5)*7 = 10*(5*7)$

Hence,

The answers are as follows:

5. $12+3 = 3+12$

7. $(6+4)+8 = 6+(4+8)$

9. $(10*5)*7 = 10*(5*7)$
