another percent problem, please explain

Your grandmother has some oranges.  She sold 40% more than she ate.  If she sold 126 oranges, how many did she eat?  Thanks!

Hi karney;

Let x= number of oranges Grandma ate.

1.4 x = 126

x=90

My grandmother wouldn't eat oranges, and
so doesn't like to sell anything.

That means I can't solve the problem.

My Uncle, however,...

Another great problem published by the Association of Math Teachers Obsessed with Fruit.

Can you please explain to me where the 1.4 came from?

Hi JoAnni;

If you think of 100% as 1 then 40% is ,4, so 40% more is 100+40 = 140 or 1 + .4 = 1.4.
