To multiply these fractions, follow these steps:
Step 1: Multiply the numerators (the numbers on top) together.
(9)(-7)(-2) = -126
Step 2: Multiply the denominators (the numbers on bottom) together.
(-2)(4)(1) = -8
Step 3: Place the product of the numerators over the product of the denominators.
-126/-8
Step 4: Simplify the fraction if possible by dividing both the numerator and denominator by their greatest common divisor.
In this case, the greatest common divisor of 126 and 8 is 2.
(-126/-8) ÷ 2/2 = 63/(-4)
Therefore, the product of (9/-2)(-7/4)(-2) can be written as the fraction 63/(-4).
