(D) Given ratios are $U: V = 6: 7$ and $V: W = 21: 6$.To find $U: V: W$,we need to make the value of $V$ common in both ratios.The value of $V$ in the first ratio is $7$ and in the second ratio is $21$.To make them equal,multiply the first ratio by $3$:$U: V = (6 	imes 3) : (7 	imes 3) = 18: 21$.Now,we have $U: V = 18: 21$ and $V: W = 21: 6$.Combining these,we get $U: V: W = 18: 21: 6$.Simplifying the ratio by dividing by $3$,we get $6: 7: 2$.Therefore,the correct option is $D$.

If $U: V = 6: 7$ and $V: W = 21: 6$,then find $U: V: W$.
