What is $50.31 into a fraction
bonufazy [111]

Answer:

50 31/100

Step-by-step explanation:

There is not much that can be done to figure out how to write 50.31 as a fraction, except to literally use what the decimal portion of your number, the .31, means. Since there are 2 digits in 31, the very last digit is the "100th" decimal place. So we can just say that .31 is the same as 31/100.

Jay works as a waiter at a restaurant.
ryzh [129]

Answer:

67.33.

Step-by-step explanation:

To figure out the tip, you need to find 20% of $52.60.

0.2×52.6=10.52

You should leave $10.52 for the waiter if you want to leave him exactly 20%.

To figure the tax, you need to find 8% of $52.60.

0.08×52.6=4.208

Next, add them up:

52.6+10.52+4.208=67.328

The total bill, including tax and tip, will be $67.33.
