Bigger one makes the same number of cookies each hour she works. She baked 1200 cookies in a six hour period of working bigger too. Makes 250 cookies each hour compare the proportional relationships which baker makes fewer cookies per hour.

To find out which baker makes fewer cookies per hour, we need to compare the rates at which each baker bakes cookies per hour.

Let's start with Bigger. We know that Bigger baked 1200 cookies in a six-hour period. So, the rate at which Bigger bakes cookies per hour is 1200 cookies / 6 hours = <<1200/6=200>>200 cookies per hour.

On the other hand, we know that the second baker bakes 250 cookies per hour.

Now, we can compare the rates of the two bakers. Bigger bakes at a rate of 200 cookies per hour, while the second baker bakes at a rate of 250 cookies per hour.

Since 200 is less than 250, it means that Bigger makes fewer cookies per hour compared to the second baker.
