Answer 1

11/16

Explanation:

12 divided by (2+2/3)^2 =1.6875

1.6875 in a decimal form is 11/16

Answer 2

`1(11)/(16)`

Explanation:

`\left(2 + (2)/(3)\right)^(2) =\left((2*3)/(1*3)+(2)/(3) \right)^(2)\\\\\\=\left( (6)/(3)+(2)/(3) \right)^(2)\\\\\\=\left( (8)/(3) \right)^(2)\\\\=(64)/(9)`

12 ÷ (2 + 2/3)² = 12 ÷ (64/9)

`= 12 *(9)/(64)\\\\= 3 *(9)/(16)\\\\= (27)/(16)\\\\\\= 1(11)/(16)`
