He read 1/2 at school and 1/10 at home. how much more of the book does he have to read?

2/5 of the book left to read

Step-by-step explanation:

1/2 + 1/10 = 5/10 + 1/10 = 6/10 reduces to 3/5

so if he read 3/5 of the book already, then he still has 2/5 of the book left to read. Because 5/5 of a book, = 1 book

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
