Hello friends, in this math homework help session, I am going to discuss about the percentages, which you study in grade VI. The term percentage comes from Latin word and means for every hundreds. Another definition is percentages is a fraction with any numbers which divide by hundredths. Percentages mean divide by 100 or per hundred. Percentages are described in two ways. The first one is fraction form. Example:-26/100 =26% The second is decimal form. Example:-33=33%.
A model for percents is a square form divided into 100 equal parts.
some examples: 33 of the 100 parts in the square to show 33 hundredths means 33/100 or 0.33 or 33%.
Money is good example for percentages. There are 100 cents in a dollar. Five cents ($.05) are 5 hundredths or (5/100) or 5% of a dollar.
Any type of problems like fractions, decimals deal with the percentages and we can easily solve them as discussed below.
Formula for percentage is used to solve different percentages problems. It is given as:-
is/of=%/100, where formula start from the left side and we can use the cross multiply it means to one multiply numerator of one fraction by denominator of another fraction.
For example:- we can find out the 20 % of 100 is.....
step 1:- is =? of=100 ,%=?
step 2:-is/100 20/100
step 3:-let's assume that a is a single digit.
Step 4:-a/100=20/100
step 5:-now we have to do cross multiplication
a*100 and 100*20
a*100=2000
divide 2000 by 100 to get the a
step 6:-now 2000/100=20 and a=20
step 7:-so,20% of 100 is 20
In this way we can calculate percentages. In the next topic we are going to discuss Proportions.
In next post we will talk on Math Blog on Grade VI. For more information on class 10 ICSE syllabus, you can visit our website
