(A) Let the number be $x$.According to the problem,adding $\frac{1}{2}$ (which is $0.5$) to the number gives $(x + 0.5)$.Multiplying this sum by $3$ results in $21$,so the equation is $(x + 0.5) 	imes 3 = 21$.Dividing both sides by $3$,we get $x + 0.5 = 7$.Subtracting $0.5$ from both sides,we get $x = 7 - 0.5 = 6.5$.Therefore,the number is $6.5$.

If $\frac{1}{2}$ is added to a number and the sum is multiplied by $3,$ the result is $21.$ Then the number is (in $.5$)
