Answer 1

Answer:

The ascending order is : $97.94 cm, 97.28 cm, 98.4/9 cm, 98.1/25 cm$

Step-by-step explanation:

⇒$Width = 9728/100, 984/(9*10), 981/(25*10), 9794/100$

⇒$Width = 9728/100, 984/90, 981/250, and 9794/100$

⇒$Width = 9794/100, 9728/100, 984/90, (981*4)/(250*4)$

⇒$Width = 9794/100, 9728/100, 984/90, 3924/1000$

⇒$Width = (9794*10)/(100*10), (9728*10)/(100*10), 984/90, 3924/1000$

⇒$Width = 97940/1000, 97280/1000, 984/90, 3924/1000$

⇒$Width = 97940/1000, 97280/1000, 3924/1000, 984/90$

⇒$Width = (97940*9)/(1000*9), (97280*9)/(1000*9), (3924*9)/(1000*9), (984*100)/(90*100)$

⇒$Width = 881460/9000, 875520/9000, 35316/9000, 98400/9000$

⇒$Width = 881460/9000, 875520/9000, 35316/9000, 98400/9000$

So, Width in the ascending order will be : 97.94 cm, 97.28 cm, 98.4/9 cm, 98.1/25 cm
