A scientist had 3 1/2 liters of vinegar. He poured 2/3 of the vinegar into beaker. He then used 3/5 of the vinegar in the beaker
for an experiment. In total, how many milliliter of vinegar did the scientist have left after experiment?
1 answer:
Answer:
A)2100 ml
Step-by-step explanation:

#First calculate the amount of vinegar not poured in the beaker:
#Calculate amount of vinegar used in experiment:
#The unused vinegar is therefore calculated by subtracting the used vinegar from the total at the start of the experiment:
Hence, the unused vinegar is 2100 ml

Answer:
Using the percentage difference formula you can find the percentage decrease.
SO its
100(new-old/new)
So we solve
10-6=4
4/10= 2/5
2/5*100=200/5
40
40 percent decrease
