The fraction or division problem becomes the # right/the total number of problems=96/120=0.8 This is a DECIMAL, so to get a PERCENT you need to MULTIPLY by 100. 80% correct is the right answer.

You would divide the small number by the big to get a decimal from which u simply multiply by 109 to get a percentage so
96 divided by 120=0.8 and simply multiply by 100 to get a percentage which is also 80% that so now hope this helps :)

Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x. 
 
                                      364 = 1.40x

Solving for x gives x = 260.

Thus, the autograph of the basketball player was worth only $260 last year.
