Unit test<br> 4% of a number is what fraction of that number?
AlexFokin [52]

Answer:

1/25

Step-by-step explanation:

Well, in order to figure this out, we need to figure out how many times 4 goes into 100, because it is 4 out of 100%.

So if you divide 100 by 4 you get 25, which means 4 goes into 100 25 times.

So the fraction would be 1/25 of the number.

Hope this helps :)

Find the most common ratio 72,12,2, 1/3,1/18
liraira [26]

Answer:

1/6

Step-by-step explanation:

To find the common ratio, you compare a few pairs of consecutive terms, by dividing an element by its predecessor.

12 / 72 = 1/6

2 / 12 = 1 / 6

1/3 / 2 = 1 / 6

The ratio is constant... so that's your common ratio to go from one term to the next.  

To go from one term to the next, you have to multiply by 1/6.
