The Missing (Unknown) Percentage Calculation
A percentage value is nothing but a fraction with a denominator of 100:
p% = p/100 = p ÷ 100.
Let p be the missing percent value that we have to calculate.
To calculate a percentage value (p%) of the number 7,700,000,000 is equivalent to multiplying them: p% × 7,700,000,000
Put all the information into an expression and then calculate the unknown missing number p:
p% × N1 = N2 ⇒ p% = N2 ÷ N1
Note: Multiply a number by the fraction 100/100 and its value doesn't change, only its form: 100/100 = 100 ÷ 100 = 100% = 1
Detailed calculation below:
p% of 7,700,000,000 = 55,020 ⇔
p% × 7,700,000,000 = 55,020 ⇒
p% =
55,020 ÷ 7,700,000,000 =
55,020 ÷ 7,700,000,000 × 100/100 =
(55,020 ÷ 7,700,000,000 × 100)/100 =
(55,020 × 100 ÷ 7,700,000,000)/100 =
(5,502,000 ÷ 7,700,000,000)/100 ≈
0.000714545455/100 =
