seema reads 1/5 of a book per hour.if she goes to sleeping after reading the book for 7/3 hours.how much part of book is now left to be read?
7/3 * 1/5 = 7/15
So, 1 - 7/15 = ?
To find out how much of the book is now left to be read, we first need to calculate how much of the book Seema has already read.
Seema reads 1/5 of the book per hour, and she has read for 7/3 hours. To find out how much of the book she has read, we multiply the rate per hour by the number of hours: (1/5) * (7/3) = 7/15.
Therefore, Seema has already read 7/15 of the book.
To determine how much of the book is now left to be read, we subtract the part Seema has already read from the total 1 whole book.
Total book - Part Seema has already read = Remaining part of the book
1 - 7/15 = 15/15 - 7/15 = 8/15
Hence, there is still 8/15 of the book left to be read.
