Find the most common ratio 72,12,2, 1/3,1/18

Mathematics
1 answer:
liraira [26]2 years ago
7 0

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.

How many grams are 2.7x10-^4 grams
andrew-mc [135]

Answer:

0,00027 grams!

Step-by-step explanation:

This is a scientific notation problem.

When a number is followed by a 10^{-1}, it means that said number has one zero at the beginning.

In this case, the number is followed by 10^{-4}, so that means that 2.7 has four zeros at the beginning. So, 2.7x10^{-4} grams is equal to 0,00027 grams! (always the comma goes after the first zero).
