Question

11/21×7/10+75/16×8/45 calculati

Answer 1

$\frac{11}{21} \times \frac{7}{10} + \frac{75}{16} \times \frac{8}{45}$

$= \frac{11 \times 7}{21 \times 10} + \frac{75 \times 8}{16 \times 45}$

$= \frac{11 \times 1}{3 \times 10} + \frac{5 \times 1}{2 \times 3}$

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

$= \frac{11}{30} + \frac{25}{30}$

$= \frac{11 + 25}{30}$

$= \frac{36}{30}$

$= \frac{6}{5}$
