Write each percentage as a fraction and as a decimal
Jlenok [28]

In order to Write down the percent divided by 100 ==>  percent/100 then  In we check if the   percent is not a whole number,if not  then we need to multiply both top and bottom by 10 for every number that comes after the decimal point. (For example, in case there is one number after the decimal point  then we use 10, if there are two numbers then use 100 and so on )   lastly  we Simplify reduce the percentage to  the fraction

Step-by-step explanation:

<u></u>

<u>To convert a Percentange  to a Fraction  we need to follow the below mentioned  steps: </u>

1) Write down the percent divided by 100 ==>  percent/100

2) In case  percent is not a whole number, if not then we need to multiply both top and bottom by 10 for every number that comes after the decimal point.

(For example, in case there is one number after the decimal point  then we use 10, if there are two numbers then use 100 and so on )

3)Then we Simplify reduce the percentage to  the fraction

For Example :<u>Convert 25% to fraction then</u>

1) 25% =25/100

2) Now in this case the percentage is a whole number so we go directly to step 3

3) <u>25/100=5/20= 1/4</u>

<u></u>

<u>25/100  is called a decimal fraction and  1/4 is called a common fraction</u>

<u></u>

<u>Now if we need to convert a Percentage into Decimal then:</u>

Let us consider the Percentage to be 25%

The easiest way to divide by 100 is to

1)we divide the number  by 100, and remove the  percentage sign. ==>25/100

2)Now we move the decimal point 2 places to the left of the percentage number ==>.25

<u>So the decimal form of the 25% is.25</u>

Consider a TV set that consumes 120 W of electric power when it is on, and is kept on for an average of 6 h per day. For a unit
Andru [333]

The cost of electricity consumed by the TV per month is <u>$4.968</u>.

In the question, we are given that a TV set consumes 120W of electric power when switched on. It is kept on for a daily average of 6 hours per day. The number of days in the month is given to be 30 days. The cost per unit of electricity is 23 cents per kWh.

We are asked to find the cost of electricity the TV consumes in the month.

The daily energy consumed by the TV = Power*Daily time = 120*6 Wh = 720 Wh.

The monthly energy consumed by the TV = Daily energy*Number of days in the month = 720*30 Wh = 21600 Wh = 21600/1000 kWh = 21.6 kWh.

Hence, the total cost of electricity the TV consumes = Monthly energy*Per unit cost = 21.6*23 cents = 496.8 cents = $496.8/100 = $4.968.

Therefore, the cost of electricity consumed by the TV per month is <u>$4.968</u>.
