mutiply 5/-19 6/-2
To multiply fractions, you simply multiply the numerators together and the denominators together.
So, to multiply 5/-19 and 6/-2:
(5/-19) * (6/-2)
= (5 * 6) / (-19 * -2)
= 30 / 38 (since -19 * -2 = 38)
The answer is 30/38. But we can simplify it further:
= 15/19 (by dividing both the numerator and denominator by the greatest common divisor which is 2)
So, the final answer is 15/19.
