Question 112882

I think you mean "----fill up her watering can----"???

once will give her 2 7/8 gal
twice will give her 4 14/8 or 5 6/8 or 5 3/4 gal---still not hardly enough
three times is the answer

ANOTHER WAY:

Let x=number of times that she needs to fill up her can

So, our equation to solve is 

(2 7/8)x=6 
2=16/8;  16/8+7/8=23/8  So:

(23/8)x=6  multiply both sides by 8

23x=48  divide both sides by 23
x= 2 2/23 times to be exact---I would just fill it three times.

CK

(2 2/23)(2 7/8)=6
(48/23)(23/8)=6
6=6
