Use a diagram to model.
$\frac{1}{3} \cdot \frac{2}{5}$
And multiply the fractions of 1/3 and 2/5. Remember rules of multiple infractions. You just multiply across. One times two is 25 times three is 15 so don't give me a fraction off to 15.
We're being asked to explain the giving diagram and our diagram shows us that effort four equals 11 corresponds to the oId a pair for 11. Well, if we think about the definition of a function we have f of X is equal to why? Well, wouldn't that correspond to the order pair X Y And indeed it would. So our input, which in this case is four, would be the X value of the order Pair in the output, which is why we correspond to the wide value and you ordered there.
Multiply fractions. Remember the rule with multiple infractions, you just multiply across. One times two is two and 12 times three is six, which will actually give you a fraction of 1/3 1 quick thing you can also do is you can do something called cross reduction so we can see that too. Divided by two gives me one which actually brings these away. So one times one gives me a one and one times three gives me a three, which gives you the same answer at the end.
