Why can you compare two fractions with the same denominator by only comparing the numerators

Think about it like this: You have two pizzas that are cut in 8 pieces. You ate 5 and your friend ate 7. Who ate more? Obviously your friend did since 7 is greater than 5.  BUT, you can only do that if both pizzas were cut in 8 pieces. If your pizza was cut in 7 and his was cut in 12, you can't just look at the numerator and say your friend ate more. You have to find a common denominator. That's why when you have a common denominator you can compare fractions because the "things" are cut into equal pieces.

What is 2(12) 3/2 in its simpilist form
Tom [10]

Answer: 2/12 --> 1/6

3/2 --> 1 1/2

Step-by-step explanation:

2/12 can be simplified by dividing the top by 2 and the bottom by two. 2 is the GCF (greatest common factor) of both 2 and 12.

3/2 is a improper fraction so you have to make it a proper fraction. To do that you get 1 and 1/2.  <-- this is for simplest form.

Hope this helped!

Find x in this right triangle.
maks197457 [2]

Answer:

<em>x = 12</em>

Solve for x:

<em>Using Pythagorean Theorem </em>

a^2 + b^2 = c^2

a = 9

c = 15

b = x

9^2 + x^2 = 15^2

81 + x^2 = 225

x^2 = 144 | sqrt

x = 12
