To convert a fraction into decimal form, simply divide the numerator by its denominator.

Example: $a/b=adivideb$

Simply divide $4$ by $9$ to find its decimal form.

$4$ cannot be divided by $9$ . In this case, add a $0$ next to $4$ and add a decimal point above the line

$9$ goes into $40$ four times. So write $4$ above the line.

Multiply $4$ to $9$ and write the answer below $40$

Subtract $36$ from $40$ and write the answer one line below.

Since we got $4$ as a remainder again, the process will repeat indefinitely.

Therefore, $2/3$ is equal to $0.4444…$ or $0.444$ rounded to three decimal places..

To convert a fraction into decimal form, simply divide the numerator by its denominator.

Example: $a/b=adivideb$

First, convert the fraction part into decimal form by dividing $1$ by $3$ .

$1$ cannot be divided by $3$ . In this case, add a $0$ next to $1$ and add a decimal point above the line

$3$ goes into $10$ three times. So write $3$ above the line.

Multiply $3$ to $3$ and write the answer below $10$

Subtract $9$ from $10$ and write the answer one line below.

Since we got $1$ as a remainder again, the process will repeat indefinitely.

Therefore, $1/3$ is equal to $0.3333…$ or $0.333$ rounded to three decimal places.

Finally, add the whole number to the quotient to get the final decimal form.

$0.333+8$ $=$ $8.333$

To convert a fraction into decimal form, simply divide the numerator by its denominator.

Example: $a/b=adivideb$

First, convert the fraction part into decimal form by dividing $4$ by $11$ .

$4$ cannot be divided by $11$ . In this case, add a $0$ next to $4$ and add a decimal point above the line

$11$ goes into $40$ three times. So write $3$ above the line.

Multiply $3$ to $11$ and write the answer below $40$

Subtract $33$ from $40$ and write the answer one line below.

$7$ cannot be divided by $11$ . In this case, add a $0$ next to $7$

$11$ goes into $70$ six times. So write $6$ above the line.

Multiply $6$ to $11$ and write the answer below $70$

Subtract $66$ from $70$ and write the answer one line below.

Since we got $4$ as a remainder again, the process will repeat indefinitely.

Therefore, $1/3$ is equal to $0.363636…$ or $0.3636$ rounded to four decimal places.

Finally, add the whole number to the quotient to get the final decimal form.

$0.3636+5$ $=$ $5.3636$

$5.3636$

To convert a fraction into decimal form, simply divide the numerator by its denominator.

Example: $a/b=adivideb$

First, convert the fraction part into decimal form by dividing $1$ by $25$ .

$1$ cannot be divided by $25$ . In this case, add a $0$ next to $1$ and add a decimal point above the line

$10$ still cannot be divided by $25$ . In this case, add another $0$ next to $10$ and also add a $0$ above the line, after the decimal point

$25$ goes into $100$ four times. So write $4$ above the line.

Multiply $4$ to $25$ and write the answer below $100$

Since $4xx25=100$ , there are no remainders in this division.

Therefore, $1/25$ is $0.04$ in decimal form.

Finally, add the whole number to the quotient to get the final decimal form.

$0.04+2$ $=$ $2.04$

To convert a fraction into decimal form, simply divide the numerator by its denominator.

Example: $a/b=adivideb$

First, convert the fraction part into decimal form by dividing $1$ by $7$ .

$1$ cannot be divided by $7$ . In this case, add a $0$ next to $1$ and add a decimal point above the line

$7$ goes into $10$ one time. So write $1$ above the line.

Multiply $1$ to $7$ and write the answer below $10$

Subtract $7$ from $10$ and write the answer one line below.

$3$ cannot be divided by $7$ . In this case, add a $0$ next to $3$

$7$ goes into $30$ four times. So write $4$ above the line.

Multiply $4$ to $7$ and write the answer below $30$

Subtract $28$ from $30$ and write the answer one line below.

$2$ cannot be divided by $7$ . In this case, add a $0$ next to $2$

$7$ goes into $20$ two times. So write $2$ above the line.

Multiply $2$ to $7$ and write the answer below $20$

Subtract $14$ from $20$ and write the answer one line below.

$6$ cannot be divided by $7$ . In this case, add a $0$ next to $6$

$7$ goes into $60$ eight times. So write $8$ above the line.

Multiply $8$ to $7$ and write the answer below $60$

Subtract $56$ from $60$ and write the answer one line below.

$4$ cannot be divided by $7$ . In this case, add a $0$ next to $4$

$7$ goes into $40$ five times. So write $5$ above the line.

Multiply $5$ to $7$ and write the answer below $40$

Subtract $35$ from $40$ and write the answer one line below.

$5$ cannot be divided by $7$ . In this case, add a $0$ next to $5$

$7$ goes into $50$ seven times. So write $7$ above the line.

Multiply $7$ to $7$ and write the answer below $50$

Subtract $49$ from $50$ and write the answer one line below.

Since we got $1$ as a remainder again, the process will repeat indefinitely.

Therefore, $1/7$ is equal to $0.dot1 4285 dot7$ .

Finally, add the whole number to the quotient to get the final decimal form.

$0.dot1 4285 dot7+9$ $=$ $9.dot1 4285 dot7$

$9.dot1 4285 dot7$
