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

Answer:

$(3 + 9) + 10 = 3 + (9 + 10)$

$12 + 10 = 3 + 19$

Step-by-step 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

$12 + 10 = 3 + 19$

$22 = 22$
