To find a percentage, you need to take a ration of the value you want and the total. In this case, 28 is the value and 50 is the total, right? Then, to make it a s

proper percentage, you multiply by 100. As such:

56%

Step-by-step explanation:

Percent literally means for each 100 ("cent" coming from the Latin word for 100). All percents can be represented as fractions with 100 in the denominator: 3%, for instance, can be written as 3/100, and 4% as 4/100 (or reduced as 1/25).

We can go the other way with fractions: 3/5 can be written as the fraction 60/100, which is 60%.

In this problem, Ainsley spends 28/50 of her allowance at the coffee shop, which can be written as 56/100, or 56%

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.
