Answer 1

Answer:

Q12. total length of rope = 68 m

        length of one piece = 4  1/4

                                          =4.25 m

        total number of the pieces= 68/4.25

  as we know, that the denominator is in decimal, we need to convert it into whole number. to d that we will have to multiply the numerator and denominator with 100 ( It is not important to multiply the fraction with 100, because our aim is to convert the denominator into whole number, which is only possible by multiplying it with 100)

=68*100/4.25*100

=6800/425 (we can now divide both the numbers)

= 16

Q13. total length of cloth = 7  1/2  

                                         =7.5

       cost of cloth per m  = 15  2/5                                        

                                        = 77

       cost of 7.5 m cloth  = 7.5*77

                                        =  ₹ 577.5
