What does fraction of G mean? (SI units)

[Kalie]

I have search my gigantic physics book everywhere for this but I can't seem to find it...does anyone know what it means

Seee the problem is
What constant acceleration, in SI units, must a car have to go from zero to 71.0 mph in 13.0 s? I solved that it was 2.44 m/s^2
but then it askes What fraction of g is this?
I have know clue what that means except it is post to be a percent...
please explain what g means

 

[Integral]

g is acceleration due to gravity, 9.81 $\frac m s$

Thank you so much

 

[berkeman]

g is acceleration due to gravity, 9.81 $\frac m s$

$$\frac{m}{s^2}$$

Can someone explain HOW to solve it?
I understand that g=gravity=9.81. So what now? How do it solve the fraction?
I know it is not 9.81/acceleration or acceleration/9.81...

Well since g * fraction = a, what does that tell you about your fraction?
