Question

Calculati (2 2/5-1 2/5-1/6)

Answer 1

Explicație pas cu pas:

$\bigg(2 \dfrac{2}{5} - 1 \dfrac{2}{5} - \dfrac{1}{6} \bigg) =$

$\bigg(\dfrac{2 \cdot 5 + 2}{5} - \dfrac{1\cdot 5 + 2}{5} -\dfrac{1}{6} \bigg) =$

$\bigg(\dfrac{12}{5} - \dfrac{7}{5} -\dfrac{1}{6} \bigg) = \dfrac{12 - 7}{5} -\dfrac{1}{6}=$

$\dfrac{5}{5} -\dfrac{1}{6}= \dfrac{^{6)} 1 \: }{1} -\dfrac{1}{6}= \dfrac{6 - 1}{6}=$

$\boxed{ \: \dfrac{5}{6} \: }$

Answer 2

$\it 2\dfrac{2}{5}-1\dfrac{2}{5}-\dfrac{1}{6}=1-\dfrac{1}{6}=\dfrac{5}{6}$
