Step-by-step explanation:
The ratio of a : b is 1 : 2
Step-by-step explanation:
A ratio is a relationship between two numbers indicating how many times the first number contains the second number
Ex: If there are eight oranges and six bananas, then the ratio of oranges to bananas is eight to six, and is written as 8 : 6, which is equivalent to the ratio 4 :3 in its simplest form
∵ a + b = 3a
- To find the ratio between a and b find b in terms of a
- Subtract a from both sides
∴ b = 2a
→ a : b
Substitute b by 2a
→ a : 2a
Divide both terms by a
→ 1 : 2
∴ a : b = 1 : 2
The ratio of a : b is 1 : 2
