What will be the product of the following:

(a) \[\frac{6}{7}\times \left( \frac{-3}{5} \right)\]

(b) \[\left( \frac{-11}{4} \right)\times \frac{5}{7}\]

Answer:

(a) \[\frac{6}{7}\times \left( -\frac{3}{5} \right)=\frac{6\times (-3)}{7\times 5}\]\[=-\frac{18}{35}\]

(b) \[\left( -\frac{11}{4} \right)\times \frac{5}{7}=\frac{\left( -11 \right)\times 5}{4\times 7}\]\[=-\frac{55}{28}\]
