Hi!
When we divide a fraction for a fraction we have to multiply the first fraction for the opposite of the second (the one we're dividing for).
Let's do an example.
16/8 : 4/6 = 16/8 * 6/4
Where necessary you can do cross-semplifying.
So, 16 and 4 can be divided both for 4.
8 and 6 both for 2.
So we have 4/4*3/1
You can also semplify numerator and denominator...
4/4 = 1
1*3 = 3

Answer:
The missing statement is ∠ACB ≅ ∠ECD
Step-by-step explanation:
Given two lines segment AC and BD bisect each other at C.
We have to prove that ΔACB ≅ ΔECD
In triangle ACB and ECD
AC=CE (Given)
BC=CD (Given)
Now to prove above two triangles congruent we need one more side or angle
so, as seen in options the angle ∠ACB ≅ ∠ECD due to vertically opposite angles
hence, the missing statement is ∠ACB ≅ ∠ECD
for mean you add every number and divide it by the amount of numbers in the data set
for median you put the numbers in order and find the middle number, if there is no middle get the mean for the two middle numbers
range is basically the lowest and highest number
