A printer has 10 rolls of newsprint in the warehouse. What fraction of this total will remain if four rolls are used?
right answer, wrong logic
What is the right logic?
To find out what fraction of the total rolls will remain if four rolls are used, we need to calculate the difference between the total number of rolls and the number of rolls used.
First, let's calculate the remaining number of rolls:
Total number of rolls in the warehouse = 10 rolls
Rolls used = 4 rolls
Remaining rolls = Total rolls - Rolls used = 10 rolls - 4 rolls = 6 rolls
Therefore, 6 rolls will remain out of the initial 10 rolls.
To express this as a fraction, we can use the remaining rolls as the numerator and the total rolls as the denominator:
Fraction remaining = Remaining rolls / Total rolls
Fraction remaining = 6 rolls / 10 rolls
The fraction remaining is 6/10, which can be simplified as 3/5.
So, if four rolls are used out of a total of 10 rolls, 3/5 of the total rolls will remain in the warehouse.
10 initially - 4 remaining = 6 used.
6 used/10 total = 6/10
