Further explanation
In mathematical calculations, the symbol of percent is used
The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)
Formula used:
\large {\boxed {\bold {Percentage \: = \: \dfrac {Total \: Section} {Total \: Amount} \: \times \: 100 \%}}}
Percentage=
TotalAmount
TotalSection
×100%
Fractions either proper or mixed (including of numerators and denominators) or decimal forms, all can be changed to a percentage
The percentage can be expressed as a decimal by moving the decimal point two places to the left
One way to convert proper fractions to percent forms is multiplying the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number.
Emily's family has a garden with a composition:
60% of their plants are flowers and 40% are vegetables. They have 50 plants growing in the garden.
Then the number of each plant is :
We multiply the percentage by the total number of plants in the garden
To multiply percent by whole number we can do with:
1. Change percent and whole number into proper fractions
2. multiply each numerator and denominator
3. Simplify the fractional form
1. Flowers
\begin{gathered}\rm =\dfrac{60}{100}\times\dfrac{50}{1}\\\\=\dfrac{3000}{100}\\\\=30\end{gathered}
