Question

8) A car wash had to make their soap last 9 days. If they only have one-ninth of a gallon of soap, how much should they use each day so it lasts 9 days?​

Answer 1

Answer:

9/81

Step-by-step explanation:

Because 1/9 is all they have so they need to reduce usage by nine so divide by nine It probably wrong tho srry :(

Answer 2

Answer:

2/81

Step-by-step explanation:

it says that 1/9 gallon has to be used over 9 days, so you would divide 1/9 by 9, which is basically multiplying 1/9 and 1/9, because you flip the second fraction around when dividing. 1/9 x 1/9 is 2/81, and it is already in simplest form, therefore the answer is 2/81 of a gallon. hope this helped
