Question 93

Solve the following:

If $\frac{1}{2}$ is substracted from a number and the difference is multiplied by 4. the result is 5. What is the number?

Answer 1

Let the number be x.
According to the equation,
$4(x-\frac{1}{2})=5\Rightarrow 4x-2=5\Rightarrow 4x=5+2\Rightarrow 4x=7\therefore x=\frac{7}{4}$
Hence, the required number is $\frac{7}{4}.$
