Answer:
-20/63
Explanation:
To divide two fractions, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is found by flipping it, so the reciprocal of 9/5 is 5/9. Here's the calculation:
(-4/7) ÷ (9/5) = (-4/7) * (5/9)
Now, multiply the numerators together and the denominators together:
Numerator: -4 * 5 = -20
Denominator: 7 * 9 = 63
So, the result in simplest form is -20/63.
