Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) to be 3. Which best describes his error?

Ankur multiplied the compatible numbers 15 and –3.

Ankur found that the quotient of a positive number and a negative number is negative.

Let x be the number of apples 
Let y be the number of oranges 

x+y≤20 
0.24x+0.8y≤12

x≤20-y 

0.24(20-y)+0.8y≤12
4.8-0.24y+0.8y≤12
0.56y≤7.2
y=12.9 (you can choose 12 here, since you can't have a fraction of an orange sold) 

x= 7.14 (again, rounding this off to 7) 

Therefore, Darcy got 12 oranges and 7 apples. 

Hope I helped :)
