Answer 1

nswer:

nswer:11:320

nswer:11:320Step-by-step explanation:

nswer:11:320Step-by-step explanation:total no. of pages in textbook of class 6th = 320

nswer:11:320Step-by-step explanation:total no. of pages in textbook of class 6th = 320total no. of pages in chapter symmetry

nswer:11:320Step-by-step explanation:total no. of pages in textbook of class 6th = 320total no. of pages in chapter symmetry=272-261 =11

nswer:11:320Step-by-step explanation:total no. of pages in textbook of class 6th = 320total no. of pages in chapter symmetry=272-261 =11therefore, ratio of number of pages to no. of pages in textbook

nswer:11:320Step-by-step explanation:total no. of pages in textbook of class 6th = 320total no. of pages in chapter symmetry=272-261 =11therefore, ratio of number of pages to no. of pages in textbook=11:320

Answer 2

GivEn:-

• Pages in Mathematics textbook of class 6 = 320 pages

• The chapter symmetry in Mathematics textbook runs from page 261 to page 272.

To find:-

• Ratio of the number of pages of this chapter to the total number of pages of the book.

SoluTion:-

$\underline{\bigstar\;\boldsymbol{As\:per\:given\:question\::}}$

• Total no. of Pages in Mathematics textbook of class 6 = 320 pages

• The chapter summetry in Mathematics textbook runs from page 261 to page 272.

Therefore,

★ Number of pages in chapter summetry = 272 - 261 + 1 = 12

So,

★ The ratio of the no. of pages of this chapter to the total number of pages of the book is,

$:\implies\sf \dfrac{No.\;of\;pages\;of\;this\;chapter}{Total\;no.\;of\;pages\;in\;textbook}\\\\ :\implies\sf \dfrac{12}{360}\\\\ :\implies\sf \cancel{ \dfrac{6}{160}}\\\\ :\implies\sf \dfrac{3}{80}\\\\ :\implies{\underline{\boxed{\sf{\purple{3:80}}}}}\;\bigstar$

$\therefore$ The ratio of the number of pages of this chapter to the total number of pages of the book is 3:80.
