Final answer:
The total number of days in the school year can be calculated using a proportion, based on the information that 65% of the year is left.
After solving, the total school year is determined to be 180 days.
Step-by-step explanation:
The student has been in school for 63 days, and there is 65% of the school year remaining.
To find the total number of days in the school year, we consider the remaining 65% as the part left after the initial 63 days.
Since the 63 days represent the 35% of the school year that has passed (100% - 65% = 35%), we can set up a proportion:
63 days is to 35% as Total days (X) is to 100%.
To solve for X, we use the equation:
63 / 0.35 = X / 1
Now, we can multiply both sides by 1 to get:
X = 63 / 0.35
Then, we do the division:
X = 180
Therefore, the total number of days in the school year is 180 days.
