Question

Leanne is building a model tower that needs to be 1.42 meters tall. The model currently is only 0.68 meter tall. How many more meters does she need to build in order to finish the model tower? Draw decimal models to find the difference.

Answer 1

Leanne needs to build an additional 0.74 meter onto her current model tower height of 0.68 meter to reach the desired height of 1.42 meters.

Step-by-step explanation:

The student's question is related to finding the additional height needed to complete a model tower. Leanne's model tower needs to be 1.42 meters tall, but it is currently 0.68 meter tall. To determine how many more meters she needs to build, we subtract the current height from the desired height:

1.42 meters - 0.68 meter = 0.74 meter

Therefore, Leanne needs to build an additional 0.74 meter to finish the model tower.
