A tree is 7.5 centimeters high. What will its height be in millimeters?
75 mm
0.75 mm
750 mm
0.0075 mm

A. 0.75mm
B. 75 mm
C. 750mm
D. 0.0075mm

# Converting Height to Millimeters

## Explanation:

To convert a measurement from centimeters to millimeters, you need to multiply the measurement by 10, as there are 10 millimeters in 1 centimeter.

In this scenario, the height of the tree is given as 7.5 centimeters. To convert it to millimeters, you can use the following calculation:

Height in millimeters = 7.5 centimeters × 10 millimeters/centimeter = 75 millimeters

Therefore, the height of the tree in millimeters is indeed 75 mm.

Option B, “75 mm,” is the correct answer, as it accurately represents the tree’s height in millimeters.

### Conclusion

Converting measurements from one unit to another is a fundamental aspect of mathematics and practical applications. In this case, understanding the relationship between centimeters and millimeters allows us to accurately express the height of the tree in millimeters.
