[ \text{Percentage} = \left( \frac{A}{B} \right) \times 100 ]
In our example:
- ( A = 10 ) (the part)
- ( B = 15 ) (the whole)
Step-by-Step Calculation
Let’s go through the calculation step-by-step to find what percent 10 is of 15:
-
Plug in the values:
[ \text{Percentage} = \left( \frac{10}{15} \right) \times 100 ]
-
Divide the numbers:
[ \frac{10}{15} = 0.6667 \quad (\text{approximately}) ]
-
Multiply by 100 to convert to percentage:
[ 0.6667 \times 100 = 66.67% ]
