- p% of A = ?
- p% of ? = A
- ?% of A = B
- fractions a/b = ?%
- relative change
- p% = ? number
- (1 + p%) × n
- (1 - p%) × n
40% of what missing number = 16?
Detailed calculations and the verification of the result
A brief introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
40% = 40 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
40% = 40/100 = 40 ÷ 100 = 0.4
100% = 100/100 = 100 ÷ 100 = 1
What does it mean:
Percentage of 40% of
which number is equal to 16?
40% of what number = 16
... is equivalent to multiplying them:
40% × number = 16
Number calculation, finding the missing unknown number
Percentage of 40% of what number = 16?
Let y be the number that we have to calculate.
40% × y = 16 =>
y =
16 ÷ 40% =
16 ÷ (40 ÷ 100) =
(100 × 16) ÷ 40 =
1,600 ÷ 40 =
40
40% of 40 = 16
Proof of the calculations
How do we check the result?
We carry out the reverse operation:
If 40% × 40 = 16 =>
Divide 16 by 40...
... And see if we get as a result: 40%
A quick note:
Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.
Calculate the percentage value:
See if we get the percentage of 40%
We will prove below that the calculations are correct.
16 ÷ 40 =
0.4 =
0.4 × 100/100 =
(0.4 × 100)/100 =
40/100 =
40%
The answer:
Percentage
of 40% of what number = 16?
40% × ? = 16
40% of 40 = 16

Three examples of problems that can be solved out using the information in this section:
Problem 1:
- 25% of the annual profit of a company was invested in buying some new equipment. The total amount invested in buying the new equipment was 100,000 dollars. What was the annual profit of the company?
- Rewrite: 25% of the Profit means 100,000 dollars => 25% × Profit = 100,000 dollars => Profit = 100,000 ÷ 25% dollars = 100,000 ÷ 25/100 dollars = 100,000 × 100/25 dollars = 100,000 × 4 dollars = 400,000 dollars;
Problem 2:
- 20% of the students in the terminal year have enrolled into the swimming class. In total, 7 students have enrolled. How many students are in the terminal year?
- Rewrite: 20% of the students means 7 students => 20% × Total number of students = 7 => The total number of students = 7 ÷ 20% = 7 ÷ 20/100 = 7 × 100/20 = 7 × 5 = 35;
Problem 3:
- In the last elections 49% of community memebrs voted for the A Party, 32% for the B Party, and the rest for the C Party. 17,920 people voted for the B Party. How many members are in the community, all in all?
- Rewrite: 32% of the total community members means 17,920 people => 32% × The total number of community members = 17,920 => The total number of community members = 17,920 ÷ 32% people = 17,920 ÷ 32/100 people = 17,920 × 100/32 people = 17,920/32 × 100 = 560 × 100 people = 56,000 people.
