Answer:
12%
Step-by-step explanation:

60+60*0.1=66
66/75=0.88=88%
Answer:
percent means <u>per hundred </u>
Between the 100 squares, 60 of them are shaded
so you do 60/100
it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100
when you calculate percentage, you do the fraction x 100
so it's 60/100 = 0.6 x100 = 60%
