Question:
The overall width in cm of several wide screen television are 97.28cm,98 4/9cm, 98 1/25 cm, and 97.94cm. Express these no.s as rational numbers in the form of p/q and arrange the width in ascending order.
Answer:
Give, width of the wide screen television are 97.28 cm, 98.4/9 cm, 98.1/25 cm, and 97.94 cm
=> Width = 9728/100, 984/(9*10), 981/(25*10), 9794/100
=> Width = 9728/100, 984/90, 981/250, and 9794/100
=> Width = 9794/100, 9728/100, 984/90, (981*4)/(250*4)
=> Width = 9794/100, 9728/100, 984/90, 3924/1000
=> Width = (9794*10)/(100*10), (9728*10)/(100*10), 984/90, 3924/1000
=> Width = 97940/1000, 97280/1000, 984/90, 3924/1000
=> Width = 97940/1000, 97280/1000, 3924/1000, 984/90
=> Width = (97940*9)/(1000*9), (97280*9)/(1000*9), (3924*9)/(1000*9), (984*100)/(90*100)
=> Width = 881460/9000, 875520/9000, 35316/9000, 98400/9000
= Width = 881460/9000, 875520/9000, 98400/9000, 35316/9000
So, width in ascending order are: 97.94 cm, 97.28 cm, 98.4/9 cm, 98.1/25 cm
