So what you have to do is make the denominators equal. You do that by finding out what number they can both go into which is 60. 12 can go into 60 5 times and so you have to do 9/12 times 5 which is 40/60. then 5 goes into 60 12 times so you have to do 1/5 times 5 which is 12/60. Then you see that 40/60 >12/60 therefore the class ate more of the pepperoni pizza

Hey there!

You have to find a common denominator. The common denominator is 60. To get 1/5 to a denominator of 60, multiply the top and bottom by 12. You get 12/60. To get 9/12 to a denominator of 60, multiply the top and bottom by 5. You get 45/60. 45/60 is more than 12/60, so the pizza that was 9/12 eaten was more. They ate more of the pepperoni pizza.

I hope this helps!

Hello!

Here we are given a composite shape, meaning that we can divide this shape up into ways that we are given formulas to solve for legs and such.

I can see here that this can be divided into a triangle and a rectangle using a horizontal line.

The leg lengths of this triangle would be 9, because it is congruent to the bottom side of the rectangle, and 7, because it is the left side minus the right side.

This would also make a right triangle, meaning we could solve for the hypotenuse utilizing the Pythagorean Theorem.

$a^2+b^2=c^2$
