Mixed Numbers to Fractions uses number line models to demonstrate how a number in mixed form can be renamed in fraction form. The illustration below was made by Mixed to Fraction Designer. ... Some textbooks call a fraction such as this improper, where the numerator is equal to or larger than.

Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. ...Step 1: Find the Lowest Common Multiple (LCM) between the denominators. ...Step 1: Convert all mixed numbers into improper fractions. ...In this second method, we will break the mixed number into wholes and parts. ...Thus, is equivalent to.

To visualize better, look at it like this:

$\frac{3r^3}{2r}$

First, see if you can simplify 3/2. You can't, so leave it like that.

The rule for exponents is you subtract the exponent from the bottom (r) from the exponent on the top ( $r^3$ )

$r^3 - r^1 = r^2$

Put that on the top, and you get

$\frac{3r^2}{2}$
