Perform the indicated operation. 15b/4 * 8/9a^2b^2
Sergio [31]

Answer:

The simplified expression is \frac{10}{3 a^2 b}

Step-by-step explanation:

The given expression is:

\frac{15b}{4} * \frac{8}{9a^2 b^2}

Multiply the items in the numerator together ( 15b * 8 = 120 b). Also multiply the items in the denominator together ( 4 * 9a²b² = 36a²b²). The expression thus becomes:

= \frac{120b}{36 a^2 b^2} \\\\

Divide both the numerator and the denominator by 12b:

= \frac{120b /12b}{36 a^2 b^2/12b}

The expression finally becomes:

= \frac{10}{3 a^2 b}
