Questions & Step-by-Step Solutions
A and B are mixed in the ratio 1:4. If there are 100 liters of the mixture, how much of A is there?
Step 1: Understand the ratio of A to B, which is 1:4.
Step 2: Add the parts of A and B together. 1 part (A) + 4 parts (B) = 5 parts total.
Step 3: Find out how much one part is worth by dividing the total mixture (100 liters) by the total parts (5). So, 100 liters ÷ 5 parts = 20 liters per part.
Step 4: Since A is 1 part, multiply the value of one part (20 liters) by the number of parts for A (1). So, A = 1 * 20 liters = 20 liters.
