Every day, the Scott Pet Store uses 3 bags of dog food to feed the dogs. For how many days will 1/2 of a bag of dog food last?

If you would like to know for how many days will 1/2 of a bag of dog food last, you can calculate this using the following steps:

1 day ... 3 bags of dog food

x days = ? ... 1/2 of a bag of dog food

1 * 1/2 = 3 * x

1/2 = 3 * x / 3

x = 1/2 * 1/3

x = 1/6 of a day

The correct result would be 1/6 of a day.
