CONVERT the FRACTION TO A DECIMAL and PER CENT
Decimal: Insert top figure in the first box and bottom figure in the secone;
%(per cent): Copy Decimal result and paste it in the empty box
%
Usually, per cents "round off" to two numbers after the ".". If the third number is more than 5 add 1 to the second number and drop the rest. If the third number is less than 5 just drop all numbers after the second one after the "."

Table of COMMON or USEFUL FRACTIONS and THEIR PER CENTS
Tasks often require "units consistency", having all fractions un-reduced. To get the Decimal, put the per cent in the first box of the Decimal coverter and put 100 in the second. A quick rule: A % is the Decimal with the point moved two place right and a Decimal is a % with the point moved two places left. 1/2=50
