Study Notes
Ratios and Their Definitions
- A ratio expresses a relationship between two numbers using division.
- The result of dividing one number by another is called the quotient, which defines the ratio.
Simplifying Ratios
- The ratio 6/9 simplifies to 2/3.
- Another example, the ratio 21:28 simplifies to 3:4.
- The ratio 25:45 simplifies to 5:9.
Ratios with Variables
- For specific values where a=3 and b=5, the ratio ( a/b ) equals 3/5.
- When ( a=3 ) and ( b=5 ), the ratio ( b/a ) results in 5/3.
- The ratio ( a/(a+b) ) where ( a=3 ) and ( b=5** gives 3/8.
- For c=4 and d=5, the ratio ( c:d ) is represented as 4:5.
