To subtract fractions, they need to have the same denominator. In this case, we can find a common denominator by multiplying 100 and 24 together to get 2400.
85/100 = 2040/240013/24 = 1300/2400
Now we can subtract the two fractions:
2040/2400 - 1300/2400 = (2040 - 1300) / 2400 = 740/2400
Finally, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 20:
740 ÷ 20 = 372400 ÷ 20 = 120
Therefore, the answer is 37/120.
