Find what percent one number is of another

Full solution

Q. If

4

is

d\%

of

8

, what is the value of

d

?

\newline

(Ignore the

\%

symbol when entering your answer. For example, if the answer is

12.4\%

, enter

12.4

.)

Set Up Equation: To find the value of d when $4$ is d% of $8$ , we need to set up the equation that represents the relationship between these numbers. The equation is: $\newline$ $4 = \frac{d}{100} \times 8$
Isolate Fraction: Next, we need to solve for d. To do this, we can divide both sides of the equation by $8$ to isolate the fraction that represents d%. $\newline$ $\frac{4}{8} = \frac{d}{100}$
Simplify Equation: Now, we simplify the left side of the equation: $\newline$ $\frac{1}{2} = \frac{d}{100}$
Multiply by $100$ : To find the value of d, we multiply both sides of the equation by $100$ : $\newline$ $100 \times \frac{1}{2} = d$
Perform Multiplication: Finally, we perform the multiplication to find the value of d: $\newline$ $100 \times \frac{1}{2} = 50$ $\newline$ So, d is $50$ .
