Question

What is a reasonable estimate for the problem 3 3/4 ×-2/5

Answer 1

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!
