Felicidad grew 17 centimeters in the past year, and is now 1. 84 meters tall
The Correct Answer and Explanation is:
To determine Felicidad’s height before her growth spurt, we need to subtract the 17 cm she grew from her current height of 1.84 meters. Here’s the calculation:
- Convert 17 centimeters to meters (since her current height is given in meters):
[
17 \, \text{cm} = 0.17 \, \text{m}
] - Subtract the growth from her current height:
[
1.84 \, \text{m} – 0.17 \, \text{m} = 1.67 \, \text{m}
]
Correct Answer:
Felicidad was 1.67 meters tall before her growth spurt.
Explanation:
This question involves understanding unit conversion and basic subtraction in the metric system. Here’s a breakdown of the solution:
- Metric Conversion:
The metric system uses meters (m) as the standard unit of length. Since her growth is given in centimeters (cm), and her height in meters, it’s necessary to convert 17 cm to meters. This is done by dividing the centimeters by 100 because there are 100 centimeters in a meter.
[
17 \, \text{cm} \div 100 = 0.17 \, \text{m}
] - Subtraction:
To find Felicidad’s height before the growth, subtract the 0.17 m she grew from her current height of 1.84 m. This ensures both values are in the same unit, allowing for accurate subtraction:
[
1.84 \, \text{m} – 0.17 \, \text{m} = 1.67 \, \text{m}
] - Verification:
After calculating, double-check the subtraction to ensure no errors occurred.
- Adding her growth of 0.17 m back to the original height of 1.67 m equals her current height of 1.84 m.
This process demonstrates the importance of consistent units and accurate arithmetic when solving real-world problems involving measurements.
