Answer: -47/100
Explanation:
To subtract fractions, we need a common denominator. In this case, the common denominator is 100, since both fractions have denominators of 8 and 100 respectively.
Let's convert both fractions to have a denominator of 100: 2/8 = 25/100 (multiplied the numerator and denominator by 25) 72/100 = 72/100 (no need to convert this fraction)
Now that both fractions have the same denominator, we can subtract the numerators: 25/100 - 72/100 = (25 - 72)/100 = -47/100
Therefore, the result of 2/8 - 72/100 is -47/100.
