Petra made the following observation: "I can write any ratio as a fraction."

Provide 3 examples that prove and explain whether or not Petra made a correct observation.

3/6 = 3:6. 1/2 = 1:2. 4/9 = 4:9.

Step-by-step explanation: Fractions and ratios are the same, in a way. Ratios are commonly written as a fraction. For example 3 cows to 6 pigs. As a ratio it would be 3:6 and as a fraction it would be 3/6. Ratios and fractions are all ways to write the same number.
