When dividing decimals to values like 10,100,1000…, simply move the decimal point to the left by the number of zeroes.
Start by converting 15 into a decimal using long division
Since 5 cannot go into 1, write 0. above it and add 0 so that 1 becomes 10
Divide 10 by 5 and write the answer after the decimal
This means 1515% is equal to 15.2%
To convert a percentage to a decimal, divide the percentage value by 100.
Since the decimal is being divided by 100, simply move the decimal point 2 places to the left.
Decimal |
= |
15.2÷100 |
Therefore, 1515% is equal to 0.152

When dividing decimals to values like 10,100,1000…, simply move the decimal point to the left by the number of zeroes.
Start by converting 18 into a decimal
Since 8 cannot go into 1, write 0. above it and add 0 so that 1 becomes 10
Divide 10 by 8 and write the answer after the decimal
Multiply 1 to 8 and write the product below 10
Subtract 8 from 10 and write the difference one line below
Since 8 cannot go into 2, add 0 so that 2 becomes 20
Divide 20 by 8 and write the answer after 0.1
Multiply 2 to 8 and write the product below 20
Subtract 16 from 20 and write the difference one line below
Since 8 cannot go into 4, add 0 so that 4 becomes 40
Divide 40 by 8 and write the answer after 0.12
This means 3718% is equal to 37.125%
To convert a percentage to a decimal, divide the percentage value by 100.
Since the decimal is being divided by 100, simply move the decimal point 2 places to the left.
Decimal |
= |
37.125÷100 |
Therefore, 3718% is equal to 0.37125

A percentage describes an amount’s relation to a whole. Dividing it by 100 converts it into a fraction.
First, change the mixed number into an improper fraction by multiplying the denominator by the whole number and then adding the numerator
3313 |
= |
(3×33)+13 |
|
|
= |
99+13 |
|
|
= |
1003% |
Then, convert the percentage to a fraction by having 100 as the percentage value’s denominator
Dividing fractions is the same as multiplying the dividend by the divisor’s reciprocal
Fraction |
= |
1003100 |
|
|
= |
1003÷100 |
Change from a fraction to division |
|
|
= |
1003×1100 |
Get the divisor’s reciprocal then multiply |
