What is a mixed fraction
A mixed fraction is a fraction that has an integer part and the numerator is less than the denominator in the fractional part. After converting a mixed fraction to an improper one, a fraction is obtained that does not have an integer part, and the numerator is greater than the denominator.
An improper fraction is a fraction in which the numerator is greater than or equal to the denominator.
In order to convert a mixed fraction to an improper one:
1. Leave the denominator the same.
2. To calculate the value of the numerator, you need to multiply the integer part by the denominator and add the resulting result to the numerator.
For example,
$3\u2064\frac{7}{9}$$=$$\mathrm{}\u2064\frac{\mathrm{(3\; \xb7\; 9)\; +\; 7}}{9}$$=$$\mathrm{}\u2064\frac{34}{9}$
