Answer:
720
Step-by-step explanation:
Add 20%+15%+35%=70%
70% of 2400 is 1680
Now subtract 1680 from 2400 which leaves 720.
C. 8/3
Simply give the two fractions the same denominator by multiplying both sides of 2/3 by 4 (2* 4 / 3 * 4 = 8/12) and both sides of 1/4 by 3 ( 1 * 3 / 4 * 3 = 3/12) to get a ratio of 8 to 3.
B is the answer
