Yes, they are

Because with fractions, you can divide. The rules for multiplying or dividing with negative numbers are that negative * or / negative = positive and that one negative * or / a positive = negative. These fractions here have one negative and one positive, making it so that when you divide, it will be negative.

Hello.


\mathrm{\displaystyle(7)/(-8) \:and\:(-7)/(8) \:are\:equal\:}

If we divide a positive number by a negative number, we get a negative number.

Let's try.

We can turn both of these fractions into decimals and see if they are equivalent.

The simplest way to turn a fraction into a decimal is divide the numerator by the denominator.


\mathrm{\displaystyle(7)/(-8) = -0.875}

Now, let's convert the second fraction into a decimal:


\mathrm{\displaystyle(-7)/(8) =-0.875}


\mathrm{-0.875=-0.875}

Therefore, the two fractions are equivalent (equal).

I hope it helps.

Have a nice day.
