Conversion of fractions into decimals
Decimals are obtained by dividing the numerator by the

denominator of a fraction.

Example 1
FOR ONLINE READING ONLY

Convert 6 into decimals.
10
Steps Solution

1. Divide the numerator by the denominator: ÷6 10,
it is not sufficient. Write 0 above the digit 6 in the 0.6
answer position, then put a decimal point. 10 6

2. Multiply: × 0 10 0.Write 0 below 6 then subtract: −0
=
6 – =0 6. 60
3. Write zero in front of 6 to make it 60, then divide: −60
÷60 =10 6. Write 6 in the answer position after 0
the decimal point.

4. Multiply: 6 10 60.Write 60 below 60 then
×
=
subtract: 60 60 0.
=
Therefore, 6 = 0.6.

Steps Solution
1. Divide the numerator by the denominator: ÷1 2,
it is not sufficient. Write 0 above the digit 1 in 0.5

the answer position, then put a decimal point. 21
2. Multiply: ×=0 2 0. Write 0 below 1then subtract: −0
1 – =0 1. 10
3. Write a zero in front of 1 to make it 10, then divide: −10
10 ÷=2 5. Write 5 in the answer position after the 0
