Answer
$\frac{2}{15}$
Work Step by Step
You are given the expression, $yz$, which means you are multiplying the variable $y$ with the variable $z$, ($y\times z$).
The values of each of these variables is given in the question.
$y = \frac{2}{3}$ and $z = \frac{1}{5}$
So, substitute these given values into the expression $yz$ and solve!
$yz= (\frac{2}{3}) \times(\frac{1}{5})$
Multiply the numbers on top, or numerators with each first, so $2$ x $1$= $2$
Then multiply the numbers at the bottom, or denominators with each other, so $3$ x $5$ = $15$
Put the fraction together again with the products, so your answer will be $\frac{2}{15}$.
