Janet reads 1/8 of her book on Monday.She reads another 2/8 of the book on Tuesday. How much of the book remain unread?
xxTIMURxx [149]
So just add 1/8 and 2/8. add 1 plus 2 and the denominator (bottom number) stays the same so you get 3/8 then subtract 8/8 minus 3/8 so just 8 minus 3 is 5 and the denominator stays the same so you end up with 5/8 so 5/8 of the book remains unread
