2) which number has the
least value?
a. 7.61
b. 6.17
c. 67.1
d. 6.71

B. 6.17  

Step-by-step explanation:

The number with the least value will have the smallest digit with the biggest place value.

Let's see how this works.

The biggest place value is the tens. The biggest digit in that column is a 7. Three other numbers are tied for being smaller, because they have no digits in the tens place.

To break the tie, we move to the ones place. Two numbers are tied, because they have sixes in the ones place.

To break the tie. we move to the tenths place. The tie is now broken, because one number has 7 in the tenths place and the other has 1.

The number with the least value is 6.17.
