You're asking to convert 3.5 to a fraction again, specifically for JHS (Junior High School) level solving. Here's how:

Write the decimal as a fraction with a denominator of 1.
$3.5 = \frac{3.5}{1}$
To remove the decimal, multiply both the numerator and the denominator by 10 (because there is one digit after the decimal point).
$\frac{3.5 \times 10}{1 \times 10} = \frac{35}{10}$
Simplify the fraction by finding the greatest common divisor (GCD) of the numerator (35) and the denominator (10).
The GCD is 5. Divide both by 5.
$\frac{35 \div 5}{10 \div 5} = \frac{7}{2}$
The fraction form of 3.5 is $\boxed{\frac{7}{2}}$ .
