Вычислите: 1) |-8,5| + |-1,2| - |6,37|; 2) |11/36| : |-2 3/4|.

1) |-8,5| + |-1,2| - |6,37| = 8,5 + 1,2 - 6,37 = 9,7 - 6,37 = 3,33.

2) $$|\frac{11}{36}| : |-2 \frac{3}{4}| = \frac{11}{36} : |-\frac{11}{4}| = \frac{11}{36} : \frac{11}{4} = \frac{11}{36} \times \frac{4}{11} = \frac{1}{9}$$

Ответ: 1) 3,33; 2) 1/9.
