Answer:
3 : 8
Step-by-step explanation:
Ratio is a comparison of two or more values are in the same unit.
- Ratio is written in its simplest form or lowest term.
- It is simplified by dividing the values by their greatest common factor (GCF).
Given:
The values must be in similar units. Convert hours to minutes:
- 1 hour = 60 minutes
- 2 hours = 2 hours × 60 minutes/hour = 120 minutes
Re-write the ratio in minutes unit:
45 minutes to 120 minutes ⇒ 45 : 120
To simplify, divide both values by their GCF 15:
- (45/15) : (120/15) = 3 : 8
Hence:
45 : 120 = 3 : 8
