Questions & Step-by-Step Solutions
A mixture of 30 liters contains two liquids A and B in the ratio 1:2. How much of liquid A is there?
Step 1: Understand the ratio of liquids A and B, which is 1:2.
Step 2: Add the parts of the ratio together: 1 (for A) + 2 (for B) = 3 parts total.
Step 3: Determine how much one part is worth by dividing the total volume (30 liters) by the total parts (3): 30 liters / 3 parts = 10 liters per part.
Step 4: Since liquid A is 1 part, multiply the value of one part (10 liters) by the number of parts for A (1): 10 liters * 1 = 10 liters of liquid A.
