Question

(3+9)+10=22. Drag the numbers and the parentheses to create an equivalent addition sentence that illustrates the associative property of addition.​

Answer 1

`(3 + 9) + 10 = 3 + (9 + 10)`

`12 + 10 = 3 + 19`

Explanation:

Given

`(3 + 9) + 10 = 22`

Required

Create equivalent expressions using associative property of addition

This property states that:

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

So, the expression can be rewritten as:

`(3 + 9) + 10 = 3 + (9 + 10)`

Solve the expression in bracket

`12 + 10 = 3 + 19`

`22 = 22`
