$\frac{7}{2}$ $7/2$

Given: $3.5$ $3.5$ .

$= 3 + 0.5$ $=3+0.5$

$= 3 + \frac{1}{2}$ $=3+1/2$

$= \frac{6}{2} + \frac{1}{2}$ $=6/2+1/2$

$= \frac{7}{2}$ $=7/2$

$\frac{7}{2}$ $7/2$

$.5 = \frac{1}{2}$ $.5= 1/2$

$3.5 = 3 \frac{1}{2}$ $3.5 = 3 1/2$

$3 \frac{1}{2} = \frac{7}{2}$ $3 1/2 = 7/2$

$3 \frac{1}{2}$ $3 1/2$

First write it as a fraction:

let:

$m = 3.5$ $m=3.5$

Multiply both sides by 10 to eliminate the decimal:

$10 m = 35$ $10m = 35$

$m = \frac{35}{10} = \frac{7}{2}$ $m=35/10=7/2$

Now we make an improper fraction by dividing and finding the remainder:

$\frac{7}{2} = 3 R 1$ $7/2 = 3 R 1$

Finally the improper fraction:

$3 \frac{1}{2}$ $3 1/2$

Just as a note mathematicians rarely use improper fractions as they are much harder to do operations on.
