Question

Which choice shows 30 + 10 + 20 rewritten correctly using the commutative property and then simplified correctly?

O 30+ 10+ 10+ 10 = 40 + 10 + 10 = 50+ 10 = 60
O 30+ 10+ 10 + 10 = 40 + 10 = 50
O 30+20+ 10 = 50 + 30 = 80
30+20 + 10 = 50+ 10 = 60

Answer 1

According to the commutative property, 30 + 10 + 20 can be rewritten correctly as 30 + 20 + 10 = 50 + 10 = 60.

Step-by-step explanation:

The commutative property states that the order of adding numbers does not change the result. So, we can rewrite 30 + 10 + 20 as 20 + 30 + 10. Simplifying, we get 50 + 10 = 60. Therefore, the correct choice is:

30 + 20 + 10 = 50 + 10 = 60
