57/100
The problem would be set up like this... 12 over x = 40 over 100 X represents the percentage we're trying to find, and the 100 below 40 percent represents 100 percent, which is constant among these types of problems. Cross multiply... 40x = 12 * 100 40x = 1200 Divide both sides by 40. x = 30.
To determine how many liters of oxygen represents 40 percent, you need to know the total volume of the mixture. For example, if you have 100 liters of gas, then 40 percent of that would be 40 liters of oxygen. Thus, the specific volume of oxygen depends on the total volume you’re considering.
30% of 40 as a fraction = 12/1 30% of 40 = 30% * 40 = 30%/100% * 40 = 12/1
