To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 180 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 180 is 100%, so we can write it down as 180=100%.
4. We know, that x is 30% of the output value, so we can write it down as x=30%.
5. Now we have two simple equations:
1) 180=100%
2) x=30%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
180/x=100%/30%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 30% of 180
180/x=100/30
(180/x)*x=(100/30)*x - we multiply both sides of the equation by x
180=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x
180/3.33333333333=x
54=x
x=54
now we have:
30% of 180=54

Answer:
The number x = 3
Step-by-step explanation:
Let 'x ' be the positive integer
Given data If the sum of five times a number and two times the same number and the same number is increased by 4 and the result is 25
sum of five times a number is 5 x and same number two times is 2 x and increased by 4 (addition) then result is equal to 25
so finally 5 x +2 x +4 = 25
7 x + 4 = 25
subtracting '4' on both sides , we get
7 x = 21
dividing '7' on both sides, we get
Therefore the number is x = 3
<u>Verification :</u>-
5 x +2 x +4 = 25
substitute x = 3 in above equation
15+6+4 = 25
25 =25
<u>Final answer</u> :-
The number is 3
