Question

34/74×122/55-34/74×48/55=

Answer 1

34/74×122/55-34/74×48/55
Сократим 34/74 до 17/37
17/37×122/55-17/37×48/55
17/37×122/55=2074/2035
17/37×48/55=816/2035
2074/2035-816/2035=34/55

Answer 2

$\frac{34}{74}* \frac{122}{55}- \frac{34}{74}* \frac{48}{55}= \frac{34}{74}*( \frac{122}{55}- \frac{48}{55})= \frac{34}{74}* \frac{74}{55}= \frac{34}{55}$
