Question

(13/21+3/14):10/27 и способ решения

Answer 1

$( \frac{13}{21} + \frac{3}{14} ): \frac{10}{27} =2 \frac{1}{4}=2,25$

1. $\frac{13}{21} + \frac{3}{14} = \frac{2*13}{2*21} + \frac{3*3}{3*14} = \frac{26}{42} + \frac{9}{42} = \frac{35}{42} = \frac{5}{6}$

2. $\frac{5}{6} : \frac{10}{27} = \frac{5*27}{6*10} = \frac{1*9}{2*2} = \frac{9}{4} = 2\frac{1}{4}$
