Thirty percent of the liquid evaporated. If 560 milliliters remain, how many milliliters evaporated?
x - 560 = .3x
Solve for x as the total amount. Multiply that by .3 to get the amount evaporated.
To find the amount of liquid that evaporated, we need to determine the initial volume of the liquid before any evaporation occurred.
Let's assume the initial volume of the liquid was Q milliliters.
Since 30% of the liquid evaporated, we can represent this as 30% of Q, which is 0.3Q.
The remaining volume of the liquid after evaporation is 560 milliliters, which we can represent as:
Q - 0.3Q = 560
Simplifying the equation, we get:
0.7Q = 560
To find the value of Q, we divide both sides of the equation by 0.7:
Q = 560 / 0.7
Q = 800
Therefore, the initial volume of the liquid before any evaporation occurred was 800 milliliters.
To find the amount of liquid that evaporated, we subtract the remaining volume from the initial volume:
800 - 560 = 240
Therefore, 240 milliliters evaporated.
To find out how many milliliters evaporated, we first need to determine the initial amount of liquid before the evaporation occurred.
Let's assume x milliliters was the original volume of the liquid.
Since 30% of the liquid evaporated, 70% remains. We can express this as a mathematical equation:
70% of x = 560 milliliters
To solve for x, we divide both sides of the equation by 70% (which is equivalent to 0.7):
x = 560 milliliters รท 0.7
Using a calculator, this calculation gives us:
x = 800 milliliters
Now that we know the initial volume of the liquid was 800 milliliters, we can calculate the amount that evaporated:
Amount evaporated = Initial volume - Remaining volume
= 800 milliliters - 560 milliliters
= 240 milliliters
Therefore, 240 milliliters evaporated from the original liquid.
