To multiply 4 by -5/8, you multiply the numbers together:
4 * (-5/8) = -20/8
To simplify the fraction, divide both the numerator and denominator by their greatest common divisor, which is 4:
-20/8 = -5/2
So, the product of 4 and -5/8 is -5/2, which can be written as -2 1/2 in mixed number form.
4 * (-5/8) = -20/8
To simplify the fraction, divide both the numerator and denominator by their greatest common divisor, which is 4:

To multiply -2 1/2 by -1 3/5, you first need to convert the mixed numbers to improper fractions:
-2 1/2 = -5/2
-1 3/5 = -8/5
Then, you multiply the two fractions:
(-5/2) * (-8/5) = 40/10 = 4
Therefore, the answer is 4.
-2 1/2 = -5/2
-1 3/5 = -8/5
Then, you multiply the two fractions:
(-5/2) * (-8/5) = 40/10 = 4
Therefore, the answer is 4.
