The answer to your question is 75 cm
Step-by-step explanation:
Data
Student calculator Demonstration calculator
width = 15 mm width = 4.5 cm
height = 250 mm height = ?
Process
1.- Convert the width of the demonstration calculator to mm
10 mm 1 cm
x 4.5 cm
x = (4.5 x 10) / 1
x = 45 mm
2.- Use proportions to find the height of the demonstration calculator
250 / 15 = x / 45
- Solve for x
x = (250 x 45) / 15
-Simplification
x = 11250 / 15
-Result
x = 750 mm
3.- Conclusion
The height of the demonstration calculator is 750 mm or 75 cm
