Question 1 of 5
Convert into decimal form
18
Incorrect
- To convert a fraction into decimal form, simply divide the numerator by its denominator.
- Example: ab=a÷b
Simply divide 1 by 8 to find its decimal form.
1 cannot be divided by 8. In this case, add a 0 next to 1 and add a decimal point above the line
8 goes into 10 one time. So write 1 above the line.
/div>
Multiply 1 to 8 and write the answer below 10
Subtract 8 from 10 and write the answer one line below.
2 cannot be divided by 8. In this case, add a 0 next to 2
8 goes into 20 two times. So write 2 above the line.
Multiply 2 to 8 and write the answer below 20
Subtract 16 from 20 and write the answer one line below.
4 cannot be divided by 8. In this case, add a 0 next to 4.
8 goes into 40 five times. So write 5 above the line.
Multiply 5 to 8 and write the answer below 40
Since 5×8=40, there are no remainders in this division.
Therefore, 18 is equal to 0.125.

Question 2 of 5
Convert into decimal form
45
Incorrect
- To convert a fraction into decimal form, simply divide the numerator by its denominator.
- Example: ab=a÷b
Simply divide 4 by 5 to find its decimal form.
4 cannot be divided by 5. In this case, add a 0 next to 4 and add a decimal point above the line
5 goes into 40 eight times. So write 8 above the line.
Multiply 8 to 5 and write the answer below 40
Since 8×5=40, there are no remainders in this division.
Therefore, 45 is equal to 0.8.

Question 3 of 5
Convert into decimal form
16
Round your answer to three decimal places
Incorrect
- To convert a fraction into decimal form, simply divide the numerator by its denominator.
- Example: ab=a÷b
Simply divide 1 by 6 to find its decimal form.
1 cannot be divided by 6. In this case, add a 0 next to 1 and add a decimal point above the line
6 goes into 10 one time. So write 1 above the line.
Multiply 1 to 6 and write the answer below 10
Subtract 6 from 10 and write the answer one line below.
4 cannot be divided by 6. In this case, add a 0 next to 4
6 goes into 40 six times. So write 6 above the line.
Multiply 6 to 6 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, 16 is equal to 0.16666… or 0.167 rounded of to three decimal places..

Question 4 of 5
Convert into decimal form
120
Incorrect
- To convert a fraction into decimal form, simply divide the numerator by its denominator.
- Example: ab=a÷b
Simply divide 1 by 20 to find its decimal form.
1 cannot be divided by 20. In this case, add a 0 next to 1 and add a decimal point above the line
10 still cannot be divided by 20. In this case, add another 0 next to 10 and also add a 0 above the line, after the decimal point
20 goes into 100 five times. So write 5 above the line.
Multiply 5 to 20 and write the answer below 100
Since 5×20=100, there are no remainders in this division.
Therefore, 120 is equal to 0.05.

Question 5 of 5
Convert into decimal form
3710
Incorrect
- To convert a fraction into decimal form, simply divide the numerator by its denominator.
- Example: ab=a÷b
First, convert the fraction part into decimal form by dividing 7 by 10.
7 cannot be divided by 10. In this case, add a 0 next to 7 and add a decimal point above the line
10 goes into 70 seven times. So write 7 above the line.
Multiply 7 to 10 and write the answer below 70
Since 7×10=70, there are no remainders in this division.
Therefore, 710 is 0.7 in decimal form.
Finally, add the whole number to the quotient to get the final decimal form.
