First you can make all the numbers decimals. (or fractions, but decimals is easiest in my opinion)

A. 4/9 = 0.444444...

B. 9/20 = 0.45

C. 0.43

D. 2/5 = 0.4

Put the numbers from least to greatest: 0.4, 0.43, 0.4444..., 0.45

You can then plot these numbers on a number line

                                   0.4      0.43        0.4444...    0.45


-1                         0                                                                             1

From this line you can see that 0.4 is farthest to the left.

Go back to your original numbers. 0.4 = 2/5 = D

The answer is D. 2/5

Hope this helps!
