This is a small text section that you can copy/paste or print-out to help your students in working out percentages.
To find what percent of number Y is of number X, you should divide number Y by number X.
Then multiply your result by 100 (x 100) and this will give you the percentage.
Your formula should look like x/y * 100 / is used on the keyboard instead of divide * is used on the keyboard instead of multiply e.g. To find out what percent 23 is of 50 23 / 50 * 100 = 46 |
To find what number X is as a total of a known percentage, you should divide (/) the known percentage by 100 and multiply (*) your result by number X.
Your formula should look like y%/100 * x e.g. To find out what 66 % is of 75 66 / 100 * 75 = 49.5 |
