Help will give crown!!
AleksandrR [38]

Answer:

Mixed number: 3\frac{15}{100}

Improper fraction: \frac{315}{100}

Step-by-step explanation:

A mixed number is a number that contains an integer part and a fraction part.

An improper fraction is a fraction where the numerator is greater than the denominator.

3.15 can be written as \frac{315}{100} in its fraction form. This would be an improper fraction since the numerator is greater than the denominator.

The mixed number is 3\frac{15}{100} since 100 goes into 315 three full times and the remainder is 15.

∴The mixed number is 3\frac{15}{100} and the improper fraction is \frac{315}{100}.
