Answer:
Explanation:
We know that 3 + 3/4=3.75.
-2/5= -04.
Any positive number times a negative number is negative.
Any negative number times a negative number is positive.
Any positive number times a positive number is positive.
3.75*-.4=-1.5.
Another way is to make it an improper fraction. 3 3/4=15/4 because 3*4=12 and 12+3=15. Multiply 15/4 by -2/5 and you have -30 in the numerator and 20 in the denominator. Your answer is -30/20 = -15/10 = -3/2 = -1.5. If you have any misunderstanding in this explanation, please let me know!
