Express

as a percent.`fraction( _N, _D )`

When the denominator is 100, you can simply take the numerator and apply the % sign:

= `fraction( _N, _D )``100 * DEC`%

reduces to `fraction( _N, _D )`

.`fraction( N, D )`

To turn a fraction into a percent, turn the fraction into a decimal and then multiply the decimal by 100.

Denominators of 10 are an easy case: The decimal form is just the numerator with the decimal place moved left by the number of 0s in the denominator - in this case 1 place.

To turn

into a decimal, perform long division, dividing `fraction( N, D )`

into `D`

(if you need help with this, try practicing some Division exercises or watching some related videos).`N`

`N` \div `D` = `DEC`

To convert this decimal into a percent, we need to multiply it by 100.

`DEC` = (100 \cdot `DEC`) \% = `roundTo( 2, 100 * DEC )`\%
