Multiply two and five-eighths negative two and three-fifths. negative six and thirty-three fortieths negative four and three-eighths four and three-eighths six and thirty-three fortieths

The correct answer is:

negative six and thirty-three fortieths

Explanation:

To multiply (2 5/8) (-2 3/5), we first change each mixed number to an improper fraction. To do this, we multiply each whole number by the denominator and add the numerator:

(2*8) + 5 = 16+5 = 21; this makes 2 5/8 = 21/8

(2*5) + 3 = 10+3 = 13; this makes - 2 3/5 = - 13/5

This gives us

(21/8) (-13/5) = (21*-13) / (8*5) = - 273/40

40 will go into 273 6 times; this gives us the number - 6. There is then 270-240 = 33 left over; this gives us 33/40, and a total of - 6 33/40.
