Question

решите (6 5/6 - 2 1/2):13

Answer 1

(6 5/6 - 2 1/2) : 13 = 1/3

1) 6 5/6 - 2 1/2 = 6 5/6 - 2 3/6 = 4 2/6 = 4 1/3

2) 4 1/3 : 13 = 13/3 : 13/1 = 13*1/3*13 = 1/3

Ответ: 1/3

Answer 2

$(6 \frac{5}{6} - 2 \frac{1}{2} ) \div 13 = ( \frac{41}{6} - \frac{5}{2} )* \frac{1}{13} = \frac{13}{3} * \frac{1}{13} = \frac{1}{3}$
