Question

Which is not equivalent to the product 1 2/3 and 3 3/5

Answer 1

ANSWER:

b. 4 19/15

STEP-BY-STEP EXPLANATION:

We calculate the product between both mixed numbers, like this:

$\begin{gathered} 1\frac{2}{3}\cdot 3\frac{3}{5} \\ \\ 1\frac{2}{3}=\frac{5}{3} \\ \\ 3\frac{3}{5}=\frac{18}{5} \\ \\ \frac{5}{3}\cdot\frac{18}{5}=\frac{90}{15}=\frac{18}{3}=6 \end{gathered}$

Therefore, of the options the only one that is not equivalent is option b. 4 19/15
