Question

Jayant read 1/7 of a book on Monday ,2/5 of book on Tuesday and 1/5 of book on Wednesday.how much part of the book is left un read?(I want with steps please)

Answer 1

Solutions :-

Given :-

Jayant read 1/7 of a book on Monday
2/5 of book on Tuesday
and 1/5 of book on Wednesday


Number of book = 1


Now,

Find the part of book which is already read:-

1/7 + 2/5 + 1/5
= (5+14+7)/35
= 26/35


Find the part of book which is left to read :-

1 - 26/35
= (35-26)/35
= 9/35



Hence,
9/35 part of the book is left to read.

Answer 2

Fraction of book read by Jayant on Monday = 1/7

Fraction of book read by Jayant on Tuesday = 2/5

Fraction of book read by Jayant on Wednesday = 1/5

fraction of book read in total = 1/7 + 1/5 + 2/5

                                                   (Make them like fractions)

                                                   So, 5/35 + 7/35 + 14/35 (As the L.C.M. of 5  

                                                    and 7 is 35 )

Therefor , Jayant read 26/35

(2nd Step)

Fraction of book Jayant read in total = 26/35

Fraction of the book = 35/35 ( which is a whole )

Fraction of book left unread = 35/35 - 26/35

                                               = 9/35

So, the answer is 9/35

Hope this helps.....
