I believe the solution is
−9 = = 7.1
<span>The place value of 1 in 5,678.321 is one-one thousands. The one digit is the third place behind the decimal point. The first place behind the decimal point is three one-tenths. The second place behind the decimal is two one-hundredths. A decimal number is a division of one. In other words, it will take a thousand one-one thousands to equal one.</span>
First try adding the ones place value, then tens, and keep on going.
Correct is A through C,, so B. Just took the quiz
