How to divide 33 photos into two groups of the ratiol is 4 to 7

Divide 33 photos into 2 groups.
The ratio of the said photo is 4 : 7
Now, we have the total number of photos which is 33, so let’s add the ratio to get the total number of ratio
=> 4 + 7 = 11
=> 33 and 11, let’s divide
=> 33 / 11 = 3, now we have the number of photos in each group.
=> 4 x 3 = 12
=> 7 x 3 = 21
Thus the ratio of photos is 12 : 21

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
