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!

She ate 90 oranges, go Grandma!
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

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.
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."

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.
