To get the result we have to find 75% of 16. 75%=0.75 0.75*16=12 - you should shade 12 triangles.
Similar situation 25%=0.25 0.25*24=6 - you should shade 6 triangles
75% is equal to 3/4 so 3*16 =48/4 which leaves you with 12 2. 25% is equal to 1/4 so 24/4 leaves you with 6 making that the amount
To shade 75% of 16 triangles, you would need to shade 12 triangles. For 25% of 24 triangles, you would need to shade 6 triangles. This is done by converting the percentages to decimals and multiplying by the total number of triangles.
