# 1% of ? = 1,121.09: Percentage of 1 (Percent) Calculated of What Missing Unknown Number Equals the Given Value, 1,121.09? How Do You Find the Missing Unknown Number? All the Steps, Explained

## 1% of what missing number = 1,121.09?

1% × ? = 1,121.09

### Brief Introduction. Finding the Missing Unknown Number. Verification of the Result. Answer

### A brief introduction. Percent, p%

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

#### 1% = 1 'out of one hundred',

#### p% is read p 'percent',

#### 1% = ^{1}/_{100} = 1 ÷ 100 = 0.01

#### 100% = ^{100}/_{100} = 100 ÷ 100 = 1

### What does it mean:

Percentage of 1% of which number is equal to 1,121.09?

#### 1% of what number = 1,121.09

#### ... is equivalent to multiplying them:

#### 1% × number = 1,121.09

## Number calculation, finding the missing unknown number

### Percentage of 1% of what number = 1,121.09?

#### Let y be the number that we have to calculate.

#### 1% × y = 1,121.09 =>

#### y =

#### 1,121.09 ÷ 1% =

#### 1,121.09 ÷ (1 ÷ 100) =

#### (100 × 1,121.09) ÷ 1 =

#### 112,109 ÷ 1 =

#### 112,109

### 1% of 112,109 = 1,121.09

## Proof of the calculations:

### How do we check the result?

#### We carry out the reverse operation:

#### If 1% × 112,109 = 1,121.09 =>

#### Divide the number 1,121.09 by the number 112,109...

#### ... And see if we get as a result: 1%

### A quick note:

^{100}/_{100} = 100 ÷ 100 = 1

#### Multiply a number by the fraction ^{100}/_{100},

... and its value doesn't change.

#### We only change the form of the result, not the result itself.

### Calculate the percentage value:

See if we get the percentage of 1%

#### 1,121.09 ÷ 112,109 =

#### 0.01 =

#### 0.01 × ^{100}/_{100} =

^{(0.01 × 100)}/_{100} =

^{1}/_{100} =

#### 1%

## So, we have proven that the calculations were correct.

The answer:

## Percentage of 1% of what number = 1,121.09?

1% × ? = 1,121.09

1% of 112,109 = 1,121.09

### 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:

- A number of 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.
