Answer:
0.7, 0.71, 0.715, 0.75
Explanation:
These numbers are all the same up to the tenths place, so you have to look in the hundredths and thousandths to tell which ones are smaller and larger.
0.7 is the smallest as it doesn't have anything in the hundredths place at all.
0.71 is the next smallest as its tenths place is smaller than 0.75's. Additionally, 0.715 has a number in hundredths place, while 0.71 does not.
0.715 is next as 0.75's hundredths place is larger than 0.715's.
So, the order is 0.7, 0.71, 0.715, and 0.75.
