Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~~~
So we know that all the denominators are multiples of 3, and the numerators are multiples of 2...
we also know that the fraction 5/6 is a dummy fraction (which means, it will not help us at all)
We know that the numerators (from 5/9 and on), are constantly multiplied by 2, and the denominators (from 5/9 and on) are constantly multiplied by 3...
So by this information, we know that the answer must be 40/243
This is because 20 * 2 = 40
And 81 * 3 = 243
So... put them together, and you get 40/243

Answer:
23.8
Step-by-step explanation:
8.5/0.5 = 17
17 x 1.4 = 23.8
Answer:
75 is 75% of 100
Step-by-step explanation:
The estimate would be 1200.
We will set up a proportion for this. 10 out of 60 of the sample were tagged, so that is the first ratio. The 200 that were tagged would be in the numerator of the second ratio (10 was the portion tagged, and 200 is the portion tagged, so they both go on top). We do not know the total number so we use a variable:
10/60 = x/200
Cross multiply:
10*x = 60*200
10x = 12000
Divide both sides by 10:
10x/10 = 12000/10
x = 1200
