To multiply 2 4/5 by -4/5, we can convert the mixed number 2 4/5 to an improper fraction.
First, we multiply the whole number 2 by the denominator 5 and add the numerator 4. This gives us 2 * 5 + 4 = 10 + 4 = 14.
Next, we convert the improper fraction 14/5 to a mixed number. The quotient is 14 divided by 5 which equals 2, and the remainder is 14 modulo 5 which equals 4. So, the mixed number equivalent of 14/5 is 2 4/5.
Now, we can multiply 2 4/5 by -4/5 as follows:
2 4/5 * -4/5 = (2 + 4/5) * -4/5
= (10/5 + 4/5) * -4/5
= (14/5) * -4/5
= (14 * -4) / (5 * 5)
= -56/25
Therefore, 2 4/5 times -4/5 equals -56/25.
