Mike has a 32 ounce drink. He drinks 8 ounces. Select the percent of ounces Mike has left from his drink

75%

Step-by-step explanation:

the percentage amount of the drink that mike drank is calculated by dividing the total drink by the amount drank. In this case that is 8/32 which gives us 0.25 or 25%.

In order to find the amount Mike has left you simply subtract the amount drank from the 1 as 1 is equal to 100% or the amount mike had at the begining.   In this case 1-0.15= 0.75 or 75%.

OR

you can also solve this by subtracting tha amount drank by the total then dividing the remaining drink by the total amount of the drink. In this case that would look like:

32-8= 24

24/32= 0.75

the answer is b.

64
