Answer:

2/8 of the book.

Step-by-step explanation:

the book represents a whole divided into 8.

Melanie read 5/8 yesterday. she read 1/8 today.

first step in this case is addition.

5/8 + 1/8 = 6/8

now how many does she have left to read?

next step is subtraction. subtract the total of what she already read to the whole.

so 1 whole is 8/8

8/8 - 6/8 = 2/8

therefore, she has 2/8 of the book left to read.

glad to help po hehehhe
