Question

Tiffany spent ( 1)/(2) of an hour playing on her phone. That used up( 1)/(3) of her battery. How long would she have to play on her phone to use the entire battery?

Answer 1

To use the entire battery, Tiffany would have to play on her phone for 40 minutes.

Step-by-step explanation:

To find out how long Tiffany would have to play on her phone to use the entire battery, we need to calculate the total amount of time it takes to use up (1)/(3) of her battery. Since Tiffany spent (1)/(2) of an hour playing on her phone and that used up (1)/(3) of her battery, we can set up a proportion to find out the total amount of time. Let x represent the total amount of time in hours:

(1/2) hour / (1/3) of battery = x hours / 1 battery

Cross-multiplying gives us:

(1/2) * 1 = (1/3) * x

Simplifying the equation gives us:

x = (1/3)/(1/2) = (1/3) * (2/1) = 2/3

So, Tiffany would need to play on her phone for 2/3 of an hour, or 40 minutes, to use the entire battery.
