Answer 1

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
