Question

21.56÷8 step by step​

Answer 1

Answer:

1. We assume, that the number 8 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 8 is 100%, so we can write it down as 8=100%.

4. We know, that x is 21.56% of the output value, so we can write it down as x=21.56%.

5. Now we have two simple equations:

1) 8=100%

2) x=21.56%

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:

8/x=100%/21.56%

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 21.56% of 8

8/x=100/21.56

(8/x)*x=(100/21.56)*x - we multiply both sides of the equation by x

8=4.6382189239332*x - we divide both sides of the equation by (4.6382189239332) to get x

8/4.6382189239332=x

1.7248=x

x=1.7248

now we have:

21.56% of 8=1.7248
