Questions & Step-by-Step Solutions
If a mixture of two liquids A and B is made in the ratio 1:4, what is the percentage of liquid A in the mixture?
Steps
Concepts
Step 1: Understand the ratio of liquids A and B, which is 1:4.
Step 2: Add the parts of the ratio together. 1 part of A + 4 parts of B = 5 total parts.
Step 3: Find the fraction of liquid A in the mixture. This is 1 part of A out of 5 total parts, so the fraction is 1/5.
Step 4: Convert the fraction to a percentage by multiplying by 100. (1/5) * 100 = 20%.
Step 5: Conclude that the percentage of liquid A in the mixture is 20%.
Ratio and Proportion
– Understanding how to calculate percentages based on given ratios.
Percentage Calculation
– Applying the formula for percentage to find the part of a whole.
