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.

schepotkina [342]

Answer:

  • 6/5 or 1.2

Step-by-step explanation:

<u>Given functions:</u>

  • f (x) = 2x + 2

<u>To find:</u>

  • (f/g) (2)

<u>Solution</u>

  • (f/g)(x) = f(x)/g(x) = (2x + 2) / (3x - 1)
  • (f/g)(2) = (2*2 + 2) / (3*2 -  1) = 6/5 = 1.2
