    Multiply by 5:
    14.18*5=70.90
    Result 70.9%

      Hello Mr. PENTIER, just thank you for the information, I've never been good at math or logic! ;)

        Oh là là !

        This isn't math yet: barely the basics of arithmetic in elementary school!

        And no logic techniques are called upon here; just a pinch of common sense...

        Best regards :-)

        Hello,

        In my (very) distant youth, at primary school, we would have sung in unison:

        I got 14.18 out of 20!

        On a scale of 1, that would be 20 times less, so I divide 14.18 by 20, that gives me 0.709!

        And on a scale of 100, that would be 100 times more, so I multiply 0.709 by 100, that gives me 70.90!

        And we didn't have calculators...

        Best regards,

        ............

      At first, I really thought it was a wrong answer. Then, I realized your trick. AWESOME
