Victoria completed 1/8 of her test in 2/5 of an hour if it koreas rate stayed the same how much of her test was finished in 1 ho
dangina [55]

Answer:

<h2>31.25%  or 1/16 of her test</h2>

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
