He currently has an test score sum of 206. He needs 280 to pass (the average score, 70, multiplied by four different test scores).
280-206=74.
He needs to get a score of 74 to pass.
Answer:. We assume, that the number 400 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 400 is 100%, so we can write it down as 400=100%.
4. We know, that x is 6.5% of the output value, so we can write it down as x=6.5%.
5. Now we have two simple equations:
1) 400=100%
2) x=6.5%
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:
400/x=100%/6.5%
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 6.5% of 400
400/x=100/6.5
(400/x)*x=(100/6.5)*x -
400=15.3846153846*x -
400/15.3846153846=x
26=x
x=26
now we have:
6.5% of 400=26
