6 5/6 ounces
(concert 4.5 into a fraction, then add)
Answer:

Step-by-step explanation:
There is not much that can be done to figure out how to write 0.8 as a fraction, except to literally use what the decimal portion of your number, the .8, means.
Since there are 1 digits in 8, the very last digit is the "10th" decimal place.
So we can just say that .8 is the same as 8/10.
The fraction is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 2.
Why divide by 2? 2 is the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of the numbers 8 and 10.
So, this fraction reduced to lowest terms is 4/5
So your final answer is: 0.8 can be written as the fraction 8/10 simplified to 4/5
Answer:
5(P - 1.00) + 3(P - 0.75)
Step-by-step explanation:
Cost of a package in store A = $P
Discount offered at store A = $1.00
Price paid per package at store A = Cost of a package in store A - Discount offered at store A
= P - 1.00
Cost of a package in store B = $P
Discount offered at store B = $0.75
Price paid per package at store B = Cost of a package in store B - Discount offered at store B
= P - 0.75
Total cost of 5 packages at store A and 3 packages at store B = 5(P - 1.00) + 3(P - 0.75)
It would be 89.
You can also just look up a list of prime numbers online.
Subtract the part from the total:
102.50 - 15 = 87.50
Now divide the remainder by rate:
87.50 / 25 = 3.5 hours
