Lets just use
for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being:
. Since then new one is equal to 1, and the original is equal to
, we see that this manipulation of the fraction causes an increase of 100%.

Answer:
-3x(2y^5+5x^3-3)
Step-by-step explanation:
-6xy^5 - 15x^4 + 9x
-6xy^5-15xx^3+9x
2*3xy^5+5+3xx^3z+3*3x
Factor:
-3x(2y^5+5x^3-3)
for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being:
