Question

Только 61,62,63
Пожалуйстаааа

Answer 1

=========== 61 ===========

$\frac{0.44 \cdot 1.8 }{4-4.6} = \frac{0.792}{-0.6} =-1.32$

=========== 62 ===========

$\frac{0.78 \cdot3.5}{6-6.7}= \frac{2.73}{-0.7}= -3.9$

=========== 63 ===========

$\frac{0.52 \cdot 6.6}{4-5.4} = \frac{ \frac{52}{100} \cdot 6 \frac{6}{10} }{-1.4} = \frac{ \frac{13}{25} \cdot \frac{33}{5} }{-1 \frac{4}{10} } =\frac{ \frac{429}{125} }{- \frac{7}{5} }= \frac{429}{125} \cdot (- \frac{5}{7} )=- \frac{429}{175} =-2 \frac{79}{175}$
