Hey there! :D

We are basically trying to find fractions that equal each other. 

3/12= 1/4  4/16= 1/4 

The first option applies. 

5/8= 5/8 (simplest form) 8/15= 8/15 (simplest form)

The second does not apply. 

1/6= 1/6 (simplest form) 5/30= 1/6 

The third option does apply. 

18/12= 3/2 3/2=3/2 (simplest form)

The fourth option does apply. 

The first, third, and fourth option are the answers. 

I hope this helps!

A proportion is two or more parts, share or numbers that are considered comparative relation to a whole. 

Basically, when you have two fractions, 2/4 and 3/6 for example, they will equal the same amount even if their numbers are different. Normally, we would reduce both of these fractions to 1/2 because 2 is 1/2 of 4 and 3 is 1/2 of 6. 

With this information you should be able to figure out which choices are proportionate and which isn't. (hint** only one answer isn't proportionate)

A factory produces 90 packages of mixed nuts in 1 min. A quality control manager selected 10 of these 90 packages at random and
valentina_108 [34]
Answer:

34

explanation:

First of all, put the numbers in order

30, 31, 31, 32, 33, 35, 35, 35, 36, 36

Then, find the middle number.
In this case, there is an even amount of numbers so, we have to pick the 2 middle numbers which is 33 and 35.

Now all you have to do is add these two numbers together then divide by 2 which will give you 34.

or, in simpler questions like this one, you can just say 34 as you know it is between 33 and 35.


In other questions, it might have and odd amount of numbers, for example:

3, 3, 5, 8, 10

so all you would do here is pick the middle number which would be 5. (it has 2 numbers on each side of it)
