Robert wrote a number on the board and then underlined the 8 in the thousandths place

Question

1848

 Which statement is true about Robert's number?

 

a) The 8 in the thousandths place is 10 times greater than the 8 in the tenths place.

b) The 8 in the thousandths place is 100 times greater than the 8 in the tenths place.

c) The 8 in the thousandths place is 1/10 the size of the 8 in the tenths place.

d) The 8 in the thousandths place is 1/100 the size of the 8 in the tenths place.

Answer 1

d) The 8 in the thousandths place is 1/100 the size of the 8 in the tenths place.

 

However, the wording is poor; it should say something like the VALUE of the 8 in the thousandths place is one hundredth of the value of an 8 if it were in the tenths place.

 

You see why? There might have been a 1, 2, 3, 4, 5, 6, 7, 9 or 0 in the tenths place.

 

And probably all digits, regardless of where written in any number, are the same SIZE.
