Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

$\frac{2}{3} ab \times \frac{ - 1}{4} {a}^{2} b \\ \\ \frac{2}{3} a \times b \times \frac{ - 1}{4} a \times a \times b \\ \\ \frac{2}{ 3 } \times \frac{ - 1}{4} \times a \times a \times a \times b \times b \\ \\ \frac{\cancel2}{ 3 } \times \frac{ - 1}{\cancel{4} \: \: {}^{2} } \times a \times a \times a \times b \times b \\ \\ \frac{ - 1}{6} {a}^{3} {b}^{2}$
