Answer:

x=\frac{536}{165}

Step-by-step explanation:

Let X be the value of 3.2484848.... infinite times

Multiply by 100

x=3.24848....\\100x = 324.8484.....

Subtract to get

100x-x = 324.8484...-3.248484....\\99x = 321.60\\x=\frac{321.6}{99} \\x=\frac{1072}{330} \\x=\frac{536}{165}

Thus the number 3.248 repeating decimal with 48 repeating in fraction form is

\frac{536}{165}
