80% percent of Steph's annual income is from her full-time job. What fraction of Steph's annual income is from her full-time job
nirvana33 [79]

Answer:

<em>\frac{4}{5} of Steph's annual income is from her full-time job.</em>

Step-by-step explanation:

Suppose, Steph's annual income is  x

Given that, 80% of Steph's annual income is from her full-time job.

So, <u>the amount of income from her full time job will be</u>:  (x\times 80\%)= (x\times\frac{80}{100})= 0.8x

Now, for finding the income from her full time job as a fraction of Steph's annual income, we just <u>need to divide "income from full time job" by "total annual income"</u>.

So, the fraction will be:  \frac{0.8x}{x}= 0.8 =\frac{8}{10}= \frac{4}{5}

That means,  \frac{4}{5} of Steph's annual income is from her full-time job.
