Question 1:

Removing the zero from 0.76 leads to .76 which is the same as before. Both lead to
in scientific notation.

Question 2:
<h3>Answer: Yes the number changes</h3>
Taking the zero out of 10.25 leads to 1.25 which is definitely a different number (and smaller). Therefore, this zero is a significant digit compared to before.
11×24=quarts per day. That's 264.
264/12=full barrels per day. That's 22.
120/22=frequency of pick ups. That's 5.45. So the barrels get picked up every 5 and a half days.
