Calculation of (-3/4) * (-2/5)

To calculate the expression (-3/4) * (-2/5), we need to multiply the fractions.

The multiplication of fractions involves multiplying the numerators together and multiplying the denominators together.

For the given expression, the calculation would be as follows:

(-3/4) * (-2/5) = (-3 * -2) / (4 * 5)

Multiplying the numerators (-3 * -2) gives us 6, and multiplying the denominators (4 * 5) gives us 20.

Therefore, (-3/4) * (-2/5) = 6/20.

Simplifying the fraction 6/20, we can divide both the numerator and denominator by their greatest common divisor, which is 2.

Dividing 6 by 2 gives us 3, and dividing 20 by 2 gives us 10.

So, (-3/4) * (-2/5) simplifies to 3/10.
