Answer 1

Answer:

Hope it helps you.

Step-by-step explanation:

Science books= 4/15

Literature books= 3/10

Maths= The rest =39

LCM of 15 and 10 =30.

LCM = 8,9/30

Science books= 8/30

Literature books= 9/30

Literature + Science books= 8+9/30

= 17/30

Therefore, maths books= 13/30 39/13=3

If 13/30= 39

1/30 books = 3

Therefore 1/30 books in the library= 3 books

Therefore literature books in the library =9/30

If 1/30= 3books

9/30= 9×3 books

27 books

ANS.(Literature books = 27 )

Answer 2

Answer:

Step-by-step explanation:

$\frac{4}{15}$ + $\frac{3}{10}$ = $\frac{8+9}{30}$

          = $\frac{17}{30}$

Therefore, the fraction of the mathematics books = $\frac{30}{30}$ - $\frac{17}{30}$ = $\frac{13}{30}$

Since the number of maths books is 39, total number of books = $\frac{13}{30}$ × X = 39

                                                                                                           $\frac{13x}{30}$ = 39

Multiply both sides by 30 to get 13x = 39(30)

                                                      13x =1170

Divide both sides by 13,the coefficient of x  ;  x=90 books

Therefore, the total number of books are 90 books

Number of science books = $\frac{4}{15}$ × 90 =24 books

Number of Literature books = $\frac{3}{10}$ × 90 =27 books
