How many liters

[ice_breaker]

Below is the math question:

A jug is 3/5 full of juice. If 100mL of juice is added to the jug it is 2/3 full. How many liters does the jug hold when full?

My answer is:

2/3 = 100 => 3/3 = 150 mL

Please advise whether my answer is correct. Thanks

suppose the jug holds x ml

so
we have:

x * 3/5 + 100 = x * 2/3

3x/5 - 2x/3 = -100

9x/15 - 10x/15 = -100

-x/15 = -100

x = 100*15 = 1500 ml.
