Question

What is 3 3/4*(-1 1/2)?

Answer 1

Answer: $-\frac{45}{8}$ or $-5\ \frac{5}{8}$

Step-by-step explanation:

Rewrite each mixed numbers as fractions:

$3\ \frac{3}{4}=\frac{(4*3)+3}{4}=\frac{12+3}{4}=\frac{15}{4}\\\\1\ \frac{1}{2}=\frac{(2*1)+1}{2}=\frac{3}{2}$

Make the multiplication:

Multiply the numerator of the first fraction by the numerator of the second fraction and  the denominator of the first fraction by the denominator of the second fraction.

$(\frac{15}{4})(-\frac{3}{2})=-\frac{45}{8}$ or $-5\ \frac{5}{8}$

Answer 2

Answer:

The correct answer is -5 5/8

Step-by-step explanation:

It is given that,  3 3/4*(-1 1/2)

To find the value of  3 3/4*(-1 1/2)

3 3/4 = 15/4 and

1 1/2 = 3/2

3 3/4*(-1 1/2) = (15/4) * (-3/2) = -45/8

-45/8 = -5 5/8

Therefore the correct answer is -5 5/8
