In the science class,
there are 3 girls and 1 boy (grade 7)
and          5 girls and 5 boys (grade 8)
There is a total of 14 pupils being 8 girls and 6 boys
The probability of choosing a boy will be \frac{6}{14}
Which can be simplified into \frac{3}{7} by dividing 2 from the numerator as well as the denominator.

A 23% increase followed by a 17% decrease is what percent change?
AVprozaik [17]
A 2.09% increase.

This is just some simple multiplication. A 23% increase is the same as multiplying by 1.23, and a 17% decrease is like multiplying by 0.83, since 100-17=83. Just multiply 1.23*0.83, which equals 1.0209, or a 2.09% increase.
