    Answer:

    distance need to walk is 3/20

    Step-by-step explanation:

    To stay healthy, Emily decided to walk for 4/5 miles everyday. She walked 2/5 mile to work and walked 1/4 mile at lunchtime.

    Target distance is 4/5 miles

    walked 2/5 miles  and walked 1/4 miles

    Total mile walked is \frac{2}{5} +\frac{1}{4}

    LCD is 20

    make the denominators same and add the fractions

    \frac{2}{5} +\frac{1}{4}\\\frac{8}{20} +\frac{5}{20}\\\\\frac{13}{20}

    Target distance is 4/5 miles

    Now subtract the miles walked from targeted distance

    \frac{4}{5} -\frac{13}{20} \\\frac{16}{20} -\frac{13}{20}\\\frac{3}{20}

    so distance need to walk is 3/20
