Answer: 
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
d = kilograms of dark chocolate
m =kilograms of milk chocolate
So, her recipe calls for twice the amount of dark chocolate as milk chocolate.
Mathematically speaking:
m = 2d
She needs to buy 120 kg, of chocolate in total. So;
m + d = 120
The following system of equations represent the situation:
Feel free to ask for more if it´s necessary or if you did not understand something.
Finding a common denominator between 10 and 12 to be 10*12=120, we can multiply 9/10 by 12/12 and 3/12 by 10/10 to get 108/120 and 30/120 respectively. Dividing the 2 (as we want to know how much 3/12 or 30/120 goes into 9/10 or 108/120), we get
(108/120)/(30/120)=(108/120)*(120/30)=(108/30)=3+18/30 (as 30 goes into 90 3 times and 108-90=18)
