Question

Express 3.28 in the form of p/q

Answer 1

328/ 100= 164/50= 82/ 25.... 82/25 is the answer

Answer 2

3.28= $\frac{328}{100}$

$=\frac{328/2}{100/2}$

$=\frac{164/2}{50/2}$

$=\frac{82}{25}$

Hence the $\frac{p}{q}$ form of 3.28 is $\frac{82}{25}$ where both numerator and  denominator are co-primes.
