b) 10 000 - (14% 18 + 24 11 + 15 x 16): 12 - 59 x 7 =​

Answer 1

Răspuns:

$\frac{526 - (51 + 49) \times 4}{3} + \frac{212}{4} = \frac{526 - 100 \times 4}{3} + \frac{212}{4} = \frac{526 - 400}{3} + \frac{212}{4} = \frac{126}{3} + \frac{212}{4} = \frac{504 + 636}{12} = \frac{1140}{12} = 95$

$10000 - \frac{ \frac{14}{100} \times 18 + 264 + 240 }{12} - 413 = 10000 - \frac{ \frac{12663}{25} }{12} - 413 = 10000 - \frac{4221}{100 } - 413 = \frac{954479}{100}$
