?% of 7 = 0.04: Given two numbers, 7 and 0.04, calculate what is the missing percent value, calculated of 7, that equals the other number, 0.04

What missing percentage p% calculated of 7 = 0.04?

Detailed calculations and verification of the result

A brief introduction. Percent, p%

'Percent (%)' means 'out of one hundred':


p% = p 'out of one hundred',


p% is read p 'percent',


p% = p/100 = p ÷ 100.


100% = 100/100 = 100 ÷ 100 = 1.


Multiply a number by the fraction 100/100,
... and its value doesn't change.


What does it mean:
What missing percent value p calculated of 7
is equal to the number 0.04?

p% of 7 = 0.04

... is equivalent to multiplying them:

p% × 7 = 0.04


Percentage calculation

What missing percentage of the number 7
is equal to the number 0.04?

Let p be the missing percent value that we have to calculate.

p% × 7 = 0.04 =>


p% =


0.04 ÷ 7 =


0.04 ÷ 7 × 100/100 =


(0.04 ÷ 7 × 100)/100 =


(0.04 × 100 ÷ 7)/100 =


(4 ÷ 7)/100


0.571428571429/100 =


0.571428571429% ≈


0.57%


0.571428571429% of 7 ≈ 0.04


The proof of the calculations

Calculate the second number:

We calculate the percentage of the first number below.

Will we get the second number, 0.04?


We will prove below that the calculations are correct:

0.571428571429% × 7 =


(0.571428571429 ÷ 100) × 7 =


0.571428571429 × 7 ÷ 100 =


4.000000000003 ÷ 100 =


0.04
