1. Answer:

   31.25%  or 1/16 of her test

   Step-by-step explanation:

   Step one:

   given

   let the total amount of her test be x

   we are told that she complete 1/8x  test in 2/5 of  an hour

   hence she completed 1/8x in 0.4 hours

   let us find the rate at which she completes are test

   rate= 1/8x/0.4

   convert the numerator to decimal number for easy computation

   rate= 0.125x/0.4

   rate=0.3125x per hour

   Step two:

   Hence 1 hour she can finish 0.3125x *1

   =0.3125x

   She can finish 31.25 % of her test in 1 hour

   or 1/16 of her test
