Answer: \(\frac{3}{500}\)
Step-by-step explanation:
Let the family's expense be x
In the Chang family's budget, 0.6% of the expenses are for internet service.
Then expense for internet service=0.6 % of x
\(\frac{0.6}{100}\times\ x\\=0.006x\)
The fraction of family's expense is for internet service =\(\frac{0.006x}{x}=\frac{0.006}{1}=\frac{6}{1000}=\frac{3}{500}\)
Hence the fraction of family's expense is for internet expense=\(\frac{3}{500}\)
