To solve this problem, we are going to set up an equation and let our unknown value be represented by the variable x. First, we must convert 25% into its decimal equivalent by dividing 25/100.
25/100 = 0.25
We should keep in mind that when we use the word “of” in math, it represents multiplication. This means that our equation should be set up with 2/3 multiplied by 27 on the left side equal to 0.25 times x on the right side, as modeled below:
(2/3)(27)=0.25x
To simplify this equation, we should perform the multiplication on the left side of the equation.
18 = 0.25x
Finally, we should divide both sides of the equation by 0.25 in order to isolate the variable x on the right side of the equation.
x = 72
Therefore, your answer and unknown number is 72.
Hope this helps!

Answer:
A centimeter is smaller than an inch, so a given length will have more centimeters than inches. This alone shows you that the NUMBER of cm units will always be greater than the number of inches, for a given measurement.
Solution:
we have given the length of the rectangular card-
and, width-
now, the area of the card will be- length×width.
so, we have-
we also have given the length of ribbon-
and, width-
so, area of the ribbon is-
length×width
now the area of shaded gray region will be-
Hence, the required expression would the above expression.
