Fractions 2

In Part 1 you learned a lot about equivalent fractions — what they mean and two ways to find them. It turns out there is a third way to find equivalent fractions, and that is the way that Einstein did. It’s the way all the world’s best mathematicians and scientists find equivalent fractions. It uses multiplication of fractions, and you are ready for it!
