Question

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

Answer 1

2/5 of the book left to read

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

Answer 2

answer 4/10 because it is how it is u know
