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.

this answer is !

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
