Question

11/21×7/10+4 11/16×8/45 va rog dau coronita!!!​

Answer 1

$\frac{11}{21} \times \frac{7}{10} + 4 \frac{11}{16} \times \frac{8}{45} =$

$\frac{11}{3} \times \frac{ 1}{10} + \frac{16 \times 4 + 11}{16} \times \frac{8}{45} =$

$\frac{11}{3} \times \frac{ 1}{10} + \frac{75}{2} \times \frac{1}{45} =$

$\frac{11}{3 \times 10} + \frac{25}{2} \times \frac{1}{15} =$

$\frac{11}{30} + \frac{25}{30} = \frac{36}{30} = \frac{6}{5}$
