WebMultiplying by 1/81 is easier to work out than 1/9 divided by 81. Always remember: dividing by a number is the same as multiplying it by it's inverse. Example: 10/2 is the same a 10*1/2=5. 20/4 is the same as 20*1/4=5. If you want to multiply instead of divide, just take the inverse or reciprocal of the number you want to divide by.
