Question

• a
. Find value of x 507
X
700​

Answer 1

Answer:

To get the solution, you are looking for, we need to point out what we know.

1. We assume, that the number 507 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 507 is 100%, so we can write it down as 507=100%.

4. We know, that x is 700% of the output value, so we can write it down as x=700%.

5. Now we have two simple equations:

1) 507=100%

2) x=700%

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:

507/x=100%/700%

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 700% of 507

507/x=100/700

(507/x)*x=(100/700)*x - we multiply both sides of the equation by x

507=0.14285714285714*x - we divide both sides of the equation by (0.14285714285714) to get x

507/0.14285714285714=x

3549=x

x=3549

now we have:

700% of 507=3549
