Vera is using her phone it battery life is down to 2/5 and it drains another 1/9 every hour how many will her battery last

Answer: We are given that Vera phone's battery life is
(2)/(5)

Also we know that, every hour phone's battery drains
=(1)/(9)

Now the number of hours her battery will last is:


((2)/(5) )/((1)/(9) ) =(2)/(5) * (9)/(1) =(18)/(5)= 3.6

Therefore her battery will lost for 3.6 hours
