Lisa set a weekly goal of jogging 18 miles. On each of the first 3 days, she jogged 2 3/8 miles. How many more miles must she jog to reach her goal?
3 * 2 3/8 = 6 9/8 = 7 1/8 miles
17 8/8 - 7 1/8 = ?
well, how far did she go altogether on the first 3 days?
10.88
To find out how many more miles Lisa must jog to reach her goal, we need to calculate the total distance she has already jogged in the first 3 days and subtract it from her weekly goal of 18 miles.
Lisa jogged 2 3/8 miles on each of the first 3 days. To find the total distance jogged, we can add up the distances for each day:
2 3/8 + 2 3/8 + 2 3/8 = (2 + 2 + 2) + (3/8 + 3/8 + 3/8) = 6 + 9/8 = 6 + 1 1/8 = 7 1/8 miles
Now we can calculate how many more miles Lisa must jog to reach her goal:
18 miles - 7 1/8 miles = 18 - 7 1/8 = 17 8/8 - 7 1/8 = (17 - 7) + (8/8 - 1/8) = 10 + 7/8 = 10 7/8 miles
Therefore, Lisa must jog 10 7/8 more miles to reach her weekly goal of 18 miles.
