At the school carnival, students are asked to guess the number of marbles in a jar to win a prize. There will be a 17% error in the gas.
How to find the percentage from the total value?
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b percent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
At the school carnival, students are asked to guess the number of marbles in a jar to win a prize.
There are 240 marbles in the jar the closest gas is 280 marbles.
280/240 = x/100.
x = 116.67%.
Now, Subtract 100% to find the percentage error.
= 117-100
= 17% error.
