Answer:
the missing value is 18.
Explanation:
First i converted the percentage to a fraction which was 30% was 3/10 or 0.3 or 3 and 100% was 1 so i took those numbers with 54, 1, 3, and Solve for an unknown value x with this fractions calculator. Find the missing fraction variable in the proportion using cross multiplication to calculate the unknown variable x. Solve the proportion between 2 fractions and calculate the missing fraction variable in equal's.
For the equation
543=x1
The cross product is
54×1=3×x
Solving for x
x=54×13
and reducing
x=18
Solution by Proportion
Since the equation is an equality
If
3 ÷ 1 = 3
Then it is true that
54 ÷ x = 3
Solving for x
x = 54 ÷ 3
x = 18
