\( \sqrt{\frac{25}{36}}-\frac{4}{3}+\frac{16}{25} \) işleminin sonucunu özdeşlikleri kullanarak bulunuz.

(c) Work out \( 4.2 \times 10^{3}+5.3 \times 10^{2} \) Give your answer in standard form.

6. \( \quad S=13 \frac{4}{9}-\left(8 \frac{1}{3}+1 \frac{6}{7}\right) \) 7. \( \quad K=3 \frac{1}{5}+\left(20 \frac{2}{15}-8 \frac{1}{3}\right) \) 8. \( \quad I=\left(15 \frac{1}{2}+15 \frac{3}{6}\right)-15 \frac{3}{10} \) 9. \( \quad N=\left(21 \frac{3}{6}+20 \frac{7}{9}\right)-10 \frac{1}{6} \)

Write \( \frac{95}{50} \) as a percentage.

Write \( \frac{39}{25} \) as a percentage.

Write \( \frac{12}{20} \) as a percentage.
