The ratio of the ages of A and B is 3:4. If A is 12 years old, how old is B? (2022)

The ratio of the ages of A and B is 3:4. If A is 12 years old, how old is B? (2022)

Step 1: Understand the ratio of ages. The ratio of A's age to B's age is 3:4.
Step 2: Identify A's age. A is 12 years old.
Step 3: Set up the relationship using the ratio. If A's age is 3 parts, then B's age is 4 parts.
Step 4: Find the value of one part. Since A's age (12) represents 3 parts, we can find the value of one part by dividing A's age by 3: 12 / 3 = 4.
Step 5: Calculate B's age. Since B's age is 4 parts, we multiply the value of one part (4) by 4: 4 * 4 = 16.
Step 6: Conclude that B is 16 years old.
