Find which is greater?

(a) 0.2 or 0.02 (b) 5.06 or 5.60 (c) 0.9 or 0.99

To find which is greater, first we have to check the whole number part. If that is equal then check the numbers one by one to the right of decimal point. The greater the number, the greater will be the value of the decimal number.

(a) 0.2 or 0.02

In 0.2, the number just after the decimal point (tenths place) is 2, whereas in 0.02, it is 0. Since, 2 > 0, we get

0.2 > 0.02

(b) 5.06 or 5.60

In 5.06, the number just after the decimal point is 0, whereas in 5.60, it is 6. Since, 6 > 0, we get

5.60 > 5.06

(c) 0.9 or 0.99

In 0.9, the number just after the decimal point (tenths place) is 9, whereas in 0.99, it is also 9. Since both are equal, we check the number at the hundredths place of 0.9, i.e., 0 and in 0.99, it is 9. Since, 9 > 0 , we get

0.99 > 0.9
