<span>Which ratio is equivalent to 21:56
</span>
Answer: 3:8
20, in total, I believe.
2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38, and of course 40
It's probably A because the fact that it is multiplied by 4 wouldn't change the number of zeros, and 10 to the 3rd power would be 1000 (if you include the X4 in this example it would be 4000).
U have a lot of calculators in google btw.
