Hello,
In this problem you have to multiply. Since, Marko runs 3/5 miles 3 times each week you will multiply \(\frac{3}{5}\) 3. Whenever you have a whole number times a fraction you add the 1 as a denominator for the whole number. So now you are doing \(\frac{3}{5}\) \(\frac{3}{1}\) multiply the numerators and denominators, 33=9 and 51=5 your final fraction will be \(\frac{9}{5}\) now change it to a mixed number and your answer will be 1\(\frac{4}{5}\). So, Marko runs 1\(\frac{4}{5}\) each week.
Have A Good Day.
