At a soccer game, 70% of the fans were rooting for the tornadoes. if 40% of the tornadoes fans were girls, what percent of the fans at the game rooting for the tornadoes were boys?

The answer is A.30%

The way I did this problem was from a number line. I don't have a one: so I'll just make one.

10%     20%    30%    40%    50%    60%    70%    80%    90%   100%

So, what you do here is you take out 30% because those are NOT tornadoes fans. 10%     20%    30%    40%    50%    60%    70% .

It says that 40% are girls so... 10%   20%    30%.

Hope you get it right!

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
