Question

how do we solve this? please answer fast​

Answer 1

Step-by-step explanation:

It is way easier than it looks!

You just have to make equivalent fractions over there, by just multiplying/dividing with same number with numerator and denominator.

For example:

$\frac{ - 5}{7} \times \frac{3}{3} = \frac{ - 15}{21} \\ so \: here \: we \: go \\ \frac{ - 5}{7} = \frac{ - 15}{21} = \frac{ - 10}{14} = \frac{ - 60}{84} \\ \frac{ - 4}{ - 20} = \frac{2}{10} = \frac{17}{85} = \frac{7}{35}$
