Answer 3

To divide a fraction by another fraction, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator.

So, for the given expression:

2/5 ÷ (-7/5)

Reciprocal of (-7/5) is (-5/7).

Now, multiply the first fraction by the reciprocal of the second fraction:

2/5 * (-5/7)

Multiply the numerators together and the denominators together:

(2 * -5) / (5 * 7) = -10 / 35

Now, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5:

-10 / 35 = -2 / 7

So, 2/5 ÷ (-7/5) equals -2/7.
