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}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%20%2B%5Cfrac%7B1%7D%7B4%7D)
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}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%20%2B%5Cfrac%7B1%7D%7B4%7D%5C%5C%5Cfrac%7B8%7D%7B20%7D%20%2B%5Cfrac%7B5%7D%7B20%7D%5C%5C%5C%5C%5Cfrac%7B13%7D%7B20%7D)
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}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D%20-%5Cfrac%7B13%7D%7B20%7D%20%5C%5C%5Cfrac%7B16%7D%7B20%7D%20-%5Cfrac%7B13%7D%7B20%7D%5C%5C%5Cfrac%7B3%7D%7B20%7D)
so distance need to walk is 3/20
