I agree with you on this problem. It is A. If that is the final answer, the negative exponent must be flipped in order to be positive. According to the equation, it is not positive so it is not a simpflied polynomial.
No because there has to be a remaining opposite persent
The answer is 3/8. You can find a common denominator of 64 among all of the fractions. From this, you can find how many orange candies there are. There is 64 candies, and 40 of them are other flavors, so there's 24 orange candies. You can create the fraction 24/64 and simplify it down to 3/8.
If you mean .152 bar as in .152152152.....then let x=.152 then:
1000x-x=152.152-.152
999x=152
x=152/999 (this cannot be reduced any further as they have no common primes)
