Given the numerical statement:
3/7 multiplied by -14/15
Solution:
In multiplying numbers, we must simply understand first the concept of multiplying, dividing, or introducing signs. If similar signs are introduced, multiplied or divided to one another, the answer will become positive, hence if the signs are opposite to one another, then the answer will become negative. In our case we have a negative number, and a positive therefore the resulting number will be negative.
= (3/7)(-14/15)
= -42/105
Factor out the greatest common factor which is 21.
= -2/5
Final answer:
= -2/5
