Answer:
3/28
Step-by-step explanation:
James read an equal number of pages of his book each night for 8 nights to prepare for his upcoming exam.
The total fraction of the book he read in 8 nights = 6/7
Hence,
8 nights = 6/7
1 night = x
Cross Multiply
8x = 6/7 × 1
x = 6/7 ÷ 8
x = 6/7 × 1/8
x = 3/28
Therefore, every night, the fraction of the book he has read is 3/28
