Round each number to the nearest tenth. About how much more did Adriana's sunflower grow than Bernard's? A. about 1.7 cm B. about 1.8 cm C. about 1.9 cm D. about 2.0 cm

Respuesta :

The answer to this question is D
The answer is D. 2.0 because you start with 4.23 8.91 and 15.12 when it says round each number to the nearest tenth you round every number on the page now you have: 4.2, 8.9, and 15.1t hen you add 4.2 and 8.9 and get 13.1

now all you have to do is subtract 15.1 - 13.1= 2.0 or 2 and that is why D. is the answer

hope this helps
