#SSC #SSCMATHEMATICS #PERCENTAGE In this video we are going to learn about PERCENTAGE.
This is Part 2 || Percentage class
---------------------------------------------------------------------------------------------------------------------------
The percent value is computed by multiplying the numeric value of the ratio by 100. For example, to find 50 apples as a percentage of 1250 apples, first compute the ratio
50
/
1250
= 0.04, and then multiply by 100 to obtain 4%. The percent value can also be found by multiplying first, so in this example the 50 would be multiplied by 100 to give 5,000, and this result would be divided by 1250 to give 4%.
To calculate a percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. For example, 50% of 40% is:
50
/
100
×
40
/
100
= 0.50 × 0.40 = 0.20 =
20
/
100
= 20%.
It is not correct to divide by 100 and use the percent sign at the same time. (E.g. 25% =
25
/
100
= 0.25, not
25%
/
100
, which actually is
25⁄100
/
100
= 0.0025. A term such as
100
/
100
% would also be incorrect, this would be read as 1 percent even if the intent was to say 100%.)
