What is 5.3 as a mixed number:

Answer: In mixed number form, 5.3 is written as 5 3/10

 

Explanation: To convert a decimal to a mixed number, separate the whole number and the fractional part.

 

Here, 5 is the whole number, and 0.3 is the decimal part. To convert 0.3 to a fraction, recognize it as 3/10 (since 0.3 means 3 tenths).

 

Combine the whole number and the fraction to get the mixed number.
