Answer:

Step-by-step explanation:

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

1.6875 in a decimal form is 11/16

Answer 2

Answer:

$1\dfrac{11}{16}$

Step-by-step explanation:

$\left(2 + \dfrac{2}{3}\right)^{2} =\left(\dfrac{2*3}{1*3}+\dfrac{2}{3} \right)^{2}\\\\\\=\left( \dfrac{6}{3}+\dfrac{2}{3} \right)^{2}\\\\\\=\left( \dfrac{8}{3} \right)^{2}\\\\=\dfrac{64}{9}$

12 ÷ (2 + 2/3)² = 12 ÷ (64/9)

                      $= 12 *\dfrac{9}{64}\\\\= 3 *\dfrac{9}{16}\\\\= \dfrac{27}{16}\\\\\\= 1\dfrac{11}{16}$
