To multiply 4 by -5/8, we can multiply the numerators together and the denominators together:
4 * -5 = -20
1 * 8 = 8
So, the result is -20/8.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 4:
-20 ÷ 4 = -5
8 ÷ 4 = 2
Therefore, the fraction -20/8 simplifies to -5/2.
A mixed number consists of a whole number and a fraction. Since -5/2 is an improper fraction (the numerator is greater than the denominator), we can express it as a mixed number by dividing the numerator by the denominator:
-5 ÷ 2 = -2 remainder 1
So, the mixed number is -2 1/2 in simplest form.
