Question

Como resolver essas questões a)(-1/6)÷(-1/7) =

Answer 1

Use aplicar a regra da fração:

$\Rightarrow \displaystyle \mathsf{\frac{-A}{-B}=\frac{A}{B}}}$

$\displaystyle \mathsf{\frac{-\frac{1}{6}}{-\frac{1}{7}}}}=\displaystyle \mathsf{\frac{\frac{1}{6}}{\frac{1}{7}}}}$

$\displaystyle \mathsf{\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}}}}$

$\displaystyle \mathsf{\frac{\frac{1}{6}}{\frac{1}{7}}=\frac{1\cdot \:7}{6\cdot \:1}}}\\\\\\\textbf{Resolver.}}\\\\\\\displaystyle \mathsf{1*7=7, \quad 6*1=6},\quad\mathsf{\frac{7}{6}=1.16 }}\\\\\\\Rightarrow\Large\boxed{\mathsf{\frac{7}{6}=1.16 }}}}$

Então, a resposta correta é 7/6=1.16.
