Answer:
The repeating decimal cost
a) As a fraction = $
b) As a mixed number = $ 
Step-by-step explanation:
The cost of making a computer component
= $3.161616
= $ 3 + 0.161616
Looking at the repeating decimal it is in 6 decimal places, hence to convert it to a fraction,
0.161616/ 1000000 × 1000000
= 161616/1000000
Therefore, the cost of making the computer component =
$3 + $161616/1000000
Step 1
We convert to a fraction
$3 + $161616/1000000
We find the LCM = 1000000
($3 × 1000000)+ ($161616× 1)/1000000
3000000 + 161616/1000000
= $ (3161616/1000000)
As a Mixed number =
