One way to check is to see if \(\dfrac{6}{15}=\dfrac{-14}{-35}\), using cross products.

Does \(6\cdot (-35)= (-14)\cdot 15\)?

Yes, \(-210=-210\)

Another way is to simplify each fraction:

\(\dfrac{6 \div 3}{15 \div 3} = \dfrac{2}{5}\) and \(\dfrac{(-14) \div (-7)}{(-35) \div (-7)} = \dfrac{2}{5}\)
