Step-by-step explanation:
Let's solve how much does it cost to have a bulb on for an hour. ⇒ 120 watt = 0.1 kilowatt per hour which costs 0.20 per kilowatt per ⇒ 0.1 kilowatt per hour* 0.20 = 0.02 dollars in an hour.
The easiest way to do it is to make the numbers into decimals. All you need to do is divide them.
To convert 3/4 into a decimal just divide 3 by 4.
3 / 4 = .75
To get 5 1/2 into a decimal just ignore the 5 for now and divide the 1 by 2.
1 / 2 = .5
Now add the 5 back on and you have 5.5
So far you have converted the equation from (3/4) / 5 1/2 to .75 / 5.5
Now just divide .75 by 5.5
.75 / 5.5 = 1.136 with the 36 repeated
