You have to solve for the amount of readers.
=500 readers.
you can easily solve it by equating the fractions 4/13 and x/91
here, we suppose x as the number of people who can bowl.
4/13=x/91
or, 4/13×91=x (divide 91 by 13)
or, x=4×7
therefore, x=28
easy peesy lemon squeezy ;-)
No, your written example is in scientific notation
