Question

$(1 + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} - \frac{1}{2} \div 5.0) \times \frac{12}{13} = 1$
​

Answer 1

Dupa ce totul a fost aplificat si adus la celasi numitor o sa fie

$(\frac{12 + 6 + 4 + 3}{12} - \frac{1}{10} ) *\frac{12}{13}$ =

$\frac{250-12}{120} *\frac{12}{13} = \frac{238}{120}*\frac{12}{13} =\frac{238}{130}$
