In the cafeteria refrigerator, cups of yogurt are kept in stacks of 9. If each worker carries no more than one stack, what is the least number of workers needed to carry cups of yogurt for a class of 42?
42/9 = 4 6/9
You'll need 5 workers.
But isn't 2 the least number?
No. 2 workers would only carry 18 cups of yogurt.
But 5 does not go into 42 evenly
No. One worker would carry less than 9 cups.
I am totally confused.
Sorry :(
Draw a picture. Divide 49 into groups of 9.
x x x x x x x x x

And so on.
