In a hundredths grid - square
In a hundredths grid, there are 10 blocks in each column. 10/100 = 10%. So one column is equal to 10%.
In a tenths grid- square
In a tenths grid, there is one block in each column. So 1/10 blocks = 10%.
10/100 can simplify into 1/10. This is why both grids are equal. They are both equivalent fractions. Both grids have columns that equal 10%.
Y+2=-3/4(x+1)
y+2=-3x/4 -3/4
y=-3x/4 - 3/4 - 2
y = -3x/4 - 3/4 - 8/4
y = -3x/4 - 11/4
There are 3 girls on each team and 4 boys on each team.
Let 
, so that differentiating both sides wrt 
gives
If 
and 
, the above reduces to
This is the slope of the tangent line, which has equation
