Elements of Division

Finding the Divident

1. When a a number is divided by 24, the quotient is 15 and the remainder is 7. Find the divident.

Solution:

$\Rightarrow$ given: Divisor = 24

$\Rightarrow$ Quotient = 15

$\Rightarrow$ Remainder = 7

$\Rightarrow$ Divident = ?

Now, Formula for finding the Divident = $\text{ Quotient } \times \text{ Divisor } + \text{ Remainder}$

$\therefore$ Divident = $15 \times 24 + 7 = 360 + 7 = 367$ Answer

Finding the Quotient

2. When 225 is divided by 13, the remainder is 4. Find the Quotient.

Solution:

$\Rightarrow$ Given, Divident = 225

$\Rightarrow$ Divisor = 13

$\Rightarrow$ Remainder = 4

$\Rightarrow$ Quotient = ?

Now, Formula for finding the Quotient = $\text{ Divisor } + \text{ Remainder}$

$\therefore$ Quotient = $13 + 4 = 17$ Answer

Finding the Divisor

3. When 429 is divided by a certain number, the Quotient is 28 and the remainder is 9. Find the Divisor.

Solution:

$\Rightarrow$ given, Divident = 429

$\Rightarrow$ Quotient = 28

$\Rightarrow$ Remainder = 9

$\Rightarrow$ Divisor = ?

Now, Formula for finding the Divisor = $\dfrac{\text{Divident } - \text{ Remainder}}{\text{Quotient}}$

$\therefore$ Divisor = $\dfrac{429 - 9}{28} = \dfrac{420}{28} = \dfrac{60}{4} = 15$ Answer

Finding the Remainder

4. When 429 is divided by 15, the Quotient is 28. Find the Remainder.

Solution:

$\Rightarrow$ given, Divident = 429,

$\Rightarrow$ Divisor = 15

$\Rightarrow$ Quotient = 28

$\Rightarrow$ Remainder = ?

Now, Formula for finding the Divisor = $\text{ Divident } - (\text{Quotient } \times \text{ Divisor})$

$\therefore$ $429 - (28 \times 15) = 429 - 420 = 9$ Answer
