Final answer:
Janet has already walked 3.065 miles on Saturday and needs to walk a total of 6 miles. By subtracting the distance walked from the total distance using decomposition, she needs to walk 2.935 miles on Sunday to reach her goal.
Step-by-step explanation:
The subject matter of the question is subtraction using decomposition. Janet needs to walk a total of 6 miles over the weekend and has walked 3.065 miles on Saturday. To find out how far she needs to walk on Sunday, we use subtraction by decomposition.
Step 1: Start by writing down the total distance to walk and the distance already walked:
- Total distance Janet aims to walk: 6 miles
- Distance walked on Saturday: 3.065 miles
Step 2: Subtract the smaller number from the larger to find the remaining distance:
6.000 miles (Total distance)
− 3.065 miles (Distance walked on Saturday)
———————
2.935 miles (Remaining distance to walk on Sunday)
Therefore, Janet needs to walk 2.935 miles on Sunday to reach her goal of 6 miles for the weekend.
