Which set of decimal numbers is in the order least to greatest?

A. .04,.004,.4,.043
B..004,.4,.043,.401
C..043,.401,.004,.04
D..004,.043,.4,.401

Think of these as money.

0.04 = 4 cents
0.004 = 4 tenths of a cent
0.4 = 40 cents
0.043 = 4.3 cents

That set is obviously not in order.

Which of the other choices do you think is in order?

i think c is the answer

Nope.

b is the answer

To determine which set of decimal numbers is in order from least to greatest, you need to compare the values of the decimals.

Let's analyze each option:

A. .04, .004, .4, .043
Starting with the smallest decimal, we have: .004 → .04 → .043 → .4
So, in increasing order, the decimals are: .004, .04, .043, .4

B. .004, .4, .043, .401
Starting with the smallest decimal, we have: .004 → .043 → .4 → .401
So, in increasing order, the decimals are: .004, .043, .4, .401

C. .043, .401, .004, .04
Starting with the smallest decimal, we have: .004 → .04 → .043 → .401
So, in increasing order, the decimals are: .004, .04, .043, .401

D. .004, .043, .4, .401
Starting with the smallest decimal, we have: .004 → .043 → .4 → .401
So, in increasing order, the decimals are: .004, .043, .4, .401

Comparing the results, option A has the decimals in the correct order from least to greatest: .004, .04, .043, .4.

Therefore, the correct answer is option A.
