Question

Vera was using her phone it’s battery life is down to 2/5 and it drains another 1/9 every hour

Answer 1

Step-by-step explanation:

We are given that Vera phone's battery life is \frac{2}{5}

2/5

Also we know that, every hour phone's battery drains =\frac{1}{9}=

9/1

Now the number of hours her battery will last is:

\frac{\frac{2}{5} }{\frac{1}{9} } =\frac{2}{5} \times \frac{9}{1} =\frac{18}{5}= 3.6

9/1 × 2/5

= 18/5

=3.6

Therefore her battery will lost for 3.6 hours
