Catarina is a botanist, studying the production of pears by two types of pear trees. Good for her. She noticed that type A trees produce 20% more pears, then type B trees did based on Catarina, his observation is the type A trees produced 144 pairs. How many pairs? Did the Type B trees produce? What a brilliant question.

Okay, so let's write out a relationship here. So the Type A trees produced 20% more pairs than type beer. So the way we're going to write that out, is by writing 1.20 be right because it's a produced 20% more we show 20% more mathematically by writing 1.2 Okay, now they're saying what if type A trees produce 144 pairs? How many of type B trees how many pairs of type B trees did it produce? So We will have 1.20 B and we just want to solve for b. So b is going to be 144 divided by 1.20, which should give us 120.
