The model shown is equal to 0.8, not 0.08.
She needs to only have 8 of the little boxes shaded.
Glad I could help, and good luck!

60 is 25% of 240 and 12 is 24% of 50
25% is a fourth of 100%. So you want to find what number 60 is a fourth of. Multiply 60 by 4.
60x4=240
24% is 4.17th of 100%. Multiply 12 by 4.17
12x4.17=50
Well, if the two angles are complementary, then that means that
(2x -9)° + (x + 30)° = 90°
