mutiply 5/-19 6/-2

Answer 1

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.
