Answer: The English teacher can review 2 essays in one hour
Step-by-step explanation: ok so if she reviewed 2/3 in 1/4 of an hour then she only needs to do 1/3 which is 1/8 of an hour so she can do another 1/3 of another essay for 1/8 of an hour and both 1/3rds would get you another 1/4 of an hour so that's 2/4 of an hour gone she can review another 2/3rds of an essay and another 2/3rds and your answer is 6/3 and that is 2.
I don't know if that makes sense it sounded better in my head, hope this helps!
