1: 80% The reason why is because if you do 4/5, you get .80, move the decimals to places to the right, and you get 80%

2: 95% Process of Elimination, and Educated Guess.

3: 33 1/3% If you do 50/150, you get 0.33333... Like I said, move the decimal point two places to the right, and you get 33.33...%

<em>I hope this helps, and Happy Holidays! :)</em>

Answer:

60 I think

Step-by-step explanation:

draw a straight line to make it a triangle then you know that angles in a triangle add up to 180.

so,

180-140=40

180-100=80

40+80=120

180-120=60

x=60

I think it's 60
