What is 57/7 ?
Division

You can decide to choose any of these but they're all the same!

8 R 1

Decimal form:

8.1 (if you round it to the nearest tenths).

8.14 (if you round it to the nearest hundredths).

8.143 (if you round it to the nearest thousandths).

Step-by-step explanation:

When you begin the division, you have to think of what is the highest number that is less than 57 that is a multiple of 7, that number is 56. 56/7 is 8 which is where I got the 8.

57 - 56 = 1 which is the remainder.

If you want to write it in decimal form, you divide the 1 by 7 and since you'll get a decimal number with 0.14.. you had that number to 8, which gives you your answer in decimal form!

Hope that helped!

the answer is b i just did that

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
