Question

2,45-0, (36)+1,6 (36)​

Answer 1

Răspuns:

$2,45 - 0,(36) + 1,6(36) = \frac{245}{100} - \frac{36}{99}  + \frac{1636 - 16}{990} = \frac{99)245}{100} - \frac{100)36}{99} + \frac{10)1620}{990} = \frac{24255- 3600 + 16200}{9900} = \frac{36855(900}{9900} =\frac{819}{220}$

Answer 2

2,45 - 0,(36) + 1,6(36)=

= 2,45 - 0,(36) + 1,(63)

= 3,45 + 0,(63) - 0,(36)

= 3,45 + 0,(27)

= 3,45 + 0,27(27)

= 3,72(27)

= (37227-372)/9900

= 36855/9900

= 819/220
