======================================================
Step-by-step explanation:
To get the relative frequency, you divide the number of times heads comes up out of the number of tosses total. Reduce the fraction as much as possible. In this case, 7 and 20 have no factors (other than 1) in common. So the fraction 7/20 cannot be reduced further.
The fraction 7/20 converts to the decimal form 0.35 after using a calculator or long division.
0.35 converts to 35% after moving the decimal over to the right two spots.
