Well 21 times 2 is 42 and 1/3 of 21 is 7 so 42+7 is 49. hope this is right
C) 1/25 for every 1 it goes up 25. therefore 1/25! hope I helped!!! brainliest would be much appreciated because I am trying to rank up!!!
The answer is b. Notice that the problem is looking for the reaction to product ratio, which is tricky because it's easy to follow the order of the column and calculate the inverse of it. Check the first ratio, 0.3/2=0.15, we can immediately choose b out of the other 4 choices.
The answer is 27.1052631579 or 27.1 if you rounded "m" to .10
