12.5%
To calculate this, you would divide 1 by the compression ratio of 8 (1/8 = 0.125), then multiply by 100 to convert to a percentage (0.125 x 100 = 12.5%).
35. If an engine has a compression ratio of 8:1, how much would the final volume be in terms of a percentage of the starting volume when the air/fuel mixture is fully compressed at the top of the compression stroke? (hint: percentage must be less (way less) than 100 and it is found using the ratio above)
