Convert 27 to a fraction:

Cross cancel the common factor:



$2 / 0.3 = $6.67
Check:
$6.67 * 0.3 = $2 :)
The equestion is
2x^2-5x-12=0
we can either try to factor, or use quadratic formula
trial and errot
(x-4)(2x+3)=0
set to zero
x-4=0
x=4
2x+3=0
2x=-3
x=-3/2
x=-3/2 or 4
Answer: 4/15
Step-by-step explanation:
Make the denominators equal first including the numerators. So, the common factor is 15. So 2/3 turns into 10/15 and 2/5 turns into 6/15. Now subtract. 10/15-6/15 is 4/15
