John has 15.50 and Salma has *15.75. Who has more money? To find this we need
compare the decimal numbers 15.50 and 15.75. To do this, we first compare the digits
n the left of the decimal point, starting from the leftmost digit. Here both the digits 1 and
to the left of the decimal point, are same. So we compare the digits on the right of the
ecimal point starting from the tenths place. We find that 5 <7, so we say
5.50 <15.75. Thus, Salma has more money than John,
If the digits at the tenths place are also same then compare the digits at the hundredths
lace and so on.
Now compare quickly, 35.63 and 35.67; 20.1 and 20.01; 19.36 and 29.36.
While converting lower units of money, length and weight to their higher units, we are
