=> 87 is the whole number where 8 is tens and 7 is the ones.
=> 6564 is the decimal numbers where 6 next to the decimal point is tenths, 5 is hundredths, 6 is the thousandths and 4 is the ten thousandths.
When you round this number to its nearest tenths, it becomes 87.7</span>

For example: I -5 I = 5

For example: I 3/4 I = 3/4

For example: I 3 I = 3

For example: I 4 I = 4
