Step-by-step solution

First, let's write the multiplication exercise in the inner parentheses as a fraction:

30/(3:132)= 30/(3:\frac{13}{2})=

Now let's flip the fraction to create a multiplication exercise:

30/(3×213)= 30/(3\times\frac{2}{13})=

Let's add 13 to the fraction's numerator in a multiplication exercise:

30/(3×213)= 30/(\frac{3\times2}{13})=

Now let's flip the fraction to create a multiplication exercise:

30×133×2= 30\times\frac{13}{3\times2}=

Let's add 30 to the fraction's numerator in a multiplication exercise:

30×133×2= \frac{30\times13}{3\times2}=

Let's break down the 30 into a smaller multiplication exercise:

10×3×133×2= \frac{10\times3\times13}{3\times2}=

Let's reduce between the 3 in the numerator and denominator:

10×132= \frac{10\times13}{2}=

Let's break down the 10 into a smaller multiplication exercise:

5×2×132= \frac{5\times2\times13}{2}=

Let's reduce between the 2 in the numerator and denominator to get:

5×13=65 5\times13=65
