Dwayne is trying to find the fraction represented by the repeating decimal 0.5. He completes the three
steps shown:
1) Let x = 0.5
2) 10x = 5.5
3)
10x =
5.5
-X =
9x = 5
0.5
What is the purpose of Step 3?
It removes the repeating part of the decimal from the equation.
o It shows that 0.5 is an irrational number.
It puts the fraction in lowest terms.
It shows that 0.5 is a terminating decimal.

It removes the repeating part of the decimal from the equation.

Step-by-step explanation:

Described here is the process of converting the repeating decimal fraction into fraction in the form of p/q

1)

2)

3)

So the purpose of step 3 here is to remove the repeating part of the decimal from the equation

Correct option is the first one.

it is true

step-by-step explanation:

all the combinations add up i used   calculator

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.
