How I stopped an Alien Invasion using Proportion

Aliens were planning to take over planet Earth , they made a deal and said if I could answer three proportional problems they would fly back to their planet and never come back to bother us .. Here are the questions they had asked me !

THE FIRST QUESTION THAT THE ALIEN ASKED ME WAS :

What is the unit rate in two pens that costs 94 cents ?

i solved it by doing this ..

THE SECOND QUESTION THAT THE ALIEN ASKED ME WAS :

At an amusement park , a new thrill ride was intorduced . It costs $7.50 for 3 rides on the Wild Slider . What is the Wild Slider's unit rate per ride ?

i solved it by doing this ..

THE THIRD AND LAST QUESTION THE ALIEN ASKED ME WAS :

Look at the pattern .Set up a proportion you could use to find the number of small squares in figure 7 .

i solved it by doing this ..

NOW THE ALIEN'S HAVE LEFT FOREVER AND HAD PROMISED THAT THEY WOULD NEVER COME BACK TO BOTHER US AGAIN ;D
