How do you fraction decimals and percents and all of that
Korvikt [17]
From fraction to decimal:  divide the numerator by the denominator 

From decimal to percent: move the decimal two places to the right. For example: 0.062=6.2%

From percent to decimal: move the decimal point two steps to the left. For example: 56%=0.56

From decimal to fraction: Rewrite the decimal number number as a fraction (example: <span>2.625=<span>2.6251</span></span>) an then Multiply by 1 to eliminate 3 decimal places, we multiply numerator and denominator by 10 cubed = 1000<span><span><span>2.625/1</span>×<span>1000/1000</span>=<span>2625/1000 and don forget to reduce if possible;)
