Clearing a decimal means multiply by a factor of 10 large enough to move the decimal point to make it a whole number.

document.write( "To clear the decimal we have to move it 3 places to the right. That means multiply by 10^3 = 100. Multiplying both sides by 100 yields

document.write( ".06 has the most decimal places, so that's the one we handle. To clear it we have to move the decimal point two places to the right, meaning multiply by 10^2 = 100. Multiplying both sides by 100 yields
