Answer:
9 has the least value in the number 7.079.
Explanation:
Let's see the value of 9 in each case.
0.29
In this case, 9 is two places after the decimal point. So it has the value of 9 hundreths, so 0.09.
7.079
In this case, 9 is three places after the decimal point. So it has the value of 9 thousandths, so 0.009.
0.9
In this case, 9 is one place after the decimal point. So it has the value of 9 tenths, so 0.9.
9.001
In this case, 9 is before the decimal point. So it has the value of 9.
So 9 has the least value in the number 7.079.
