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}

Answer:

\frac{536}{165}

Step-by-step explanation:

Step 1: let's call x the repeating decimal.

So, x=32.2484848484848...

Step 2: identify the number of digits that repeats.

We see that two digits repeat 4 and 8.

Step 3: multiply 100 at each side of the equation, two digits, two zeros, that's why is 100.

100x=324.84848484848...

Step 4: we subtract the repeating decimal the last expression:

100x-x=(324.8484848...)-(3.2484848...)\\99x=321.6

Step 5: solve for x.

x=\frac{321.6}{99}

In this case, we have to multiply each part of the fraction by 10 to get rid of the decimal number.

x=\frac{321.6(10)}{99(10)}=\frac{3216}{990}=\frac{536}{165}

Therefore, the repeating decimal is equal to \frac{536}{165}
