Which of the following decimal number cannot be converted to a mixed number?
⇒ A decimal number is a number that consists of a whole number and a fractional part.
⇒The decimal point separates the whole number from the fractional part.
Note: Look at the number to the left of the decimal.
⇒ If it is zero, the decimal can be converted to a proper fraction.
⇒ If it is not zero, the decimal can be converted to a mixed number.
In the number 1.15, the decimal point separates the whole number 1 from the fractional part 15. Hence 1.15 can be converted into a proper fraction
Similarly, 2.15 and 10.15 can also be converted to a mixed number.
∴0.15 cannot be converted to a mixed number, as there is no whole part in 0.15.
