Answer:

<h3>Yes, it should be -2.</h3>

Step-by-step explanation:

To solve this, you have to divide this fraction from left to right.

<h3>What is a fraction?</h3>

Fraction is a division or part of a whole number.

<u>First, do apply the fraction rule.</u>

\rightarrow: \sf{\dfrac{A}{B}\div \dfrac{C}{D}=\dfrac{A}{B}\times \dfrac{D}{C}}

\sf{-\dfrac{1}{50}\times \dfrac{100}{1}}

<u>Cancel the common factor of 50.</u>

\sf{-\dfrac{2}{1} }

<u>Divide.</u>

-2/1=-2

\rightarrow: \boxed{\sf{-2}}

So, the final answer is -2.

I hope this helps, let me know if you have any questions.

If electricity costs 5 cents per kilowatt-hour, how much does it cost to run an 80-watt light bulb for 24 hours?96.0 cents 4.2 c
joja [24]

We are given the electricity cost as 5 cents per kilowatt-hour. We should notice that the cost is actually in the form of:

electrical cost = cost / (power * time)

Therefore to get a number which is in terms of cents alone (cost alone), therefore we should multiply the given electrical cost value with the power and time.

Power = 80 watt = 0.08 kilowatt

Time = 24 hours

 

Therefore the cost is calculated as:

cost = electrical cost * power * time

cost = [5 cents / (kilowatt hour)] (0.08 kilowatt) (24 hour)

cost = 9.6 cents

 

Answer:

<span>9.6 cents</span>
