Re: Least value in decimal


C is the least (0.015); Second part : 0.501 is bigger of the two.

hi Zeeshan 01

A.     0.105
B.     0.501
C.     0.015
D.    0.15

Check the largest digit first.

units:  all have a zero so go on to the tenths digit  0.x

C has a zero.  The others all have a bigger tenths digit so C is smallest.

Another example:

A   0.035
B   0.041
C   0.0356
D   0.0305

Check units:

All have a zero.

Check tenths (0.x):

All have a zero again.

Check hundredths (0,0x)

A has a 3, B has a 4, C has a 3, D has a 3.  So reject B but keep looking at the thousandth digits (0.00x) for A, C and D.

A has a 5, C has a 5, D has a zero.  So D is the smallest.
