  1. thank youuuuuuuuuuuuuuuuu!!!!!!!!!!!!!!!

    very helpful, i’m going to dubai in a few weeks and to convert the currency (so that i can know how much a price is in pounds) i have to divide by 5.4, so i use this, dividing by 5 instead, not as accurate but close enough!!! thanks!!!!!!!!

    easiest way to divide by 5:

    divide by 10
    multiply by 2

    take any number…say 90 for example:

    divide by 10 = 9
    9 times 2 = 18

    voila! 18 is the answer to 90 / 5!
