Answer:
<u>So option 4; </u>
<u> is the correct option</u>
Step-by-step explanation:
First, we need to convert
so it's denominator is 100. To do so, we will multiply the numerator and denominator by 10
![\frac{2}{10} *\frac{10}{10} = \frac{20}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2A%5Cfrac%7B10%7D%7B10%7D%20%3D%20%5Cfrac%7B20%7D%7B100%7D)
Second, we need to add the two fractions to get the current total distance walked. Remember, when adding fractions, the denominator does not change.
![\frac{45}{100} + \frac{20}{100} = \frac{65}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B100%7D%20%2B%20%5Cfrac%7B20%7D%7B100%7D%20%3D%20%5Cfrac%7B65%7D%7B100%7D)
Now that we have the total distance walked, we need to subtract that to 1 mile. ![1mile=\frac{1}{1} = \frac{10}{10} =\frac{100}{100}](https://tex.z-dn.net/?f=1mile%3D%5Cfrac%7B1%7D%7B1%7D%20%3D%20%5Cfrac%7B10%7D%7B10%7D%20%3D%5Cfrac%7B100%7D%7B100%7D)
![\frac{100}{100} -\frac{65}{100} = \frac{35}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B100%7D%7B100%7D%20-%5Cfrac%7B65%7D%7B100%7D%20%3D%20%5Cfrac%7B35%7D%7B100%7D)
So option 4;
is the correct option
Year 1: 7lbs x 3years= 21lbs
Year 2: 21lbs x 3years = 63lbs
