Answer 2

Explicație pas cu pas:

ღSalutare!ღ

$4 \times \frac{1}{7} + 2.72 = \frac{4 \times 1}{7} + 2.72 = ^{100)} \frac{4}{7} + ^{7)} \frac{272}{100} = \frac{400}{700} + \frac{1904}{700} = \frac{400 + 1904}{700} = \frac{2304}{700} ^{(2} = \frac{1152}{350} ^{(2} = \red{ \frac{576}{175} }$

Succes!;)
