Mia is a student. In her final year, she spent 1/5 of her day watching TV and 1/4 of the time left on studying. How many minutes did she spend studying each day?
If Mia spent 1/5 of her day watching TV, her remaining time in a day is 5/5 - 1/5 = 4/5 for other things.
So, the time left is 24 * 4/5 = 
<gadget id="calculator">24*4/5</gadget>
<output>96/5 = around 19.2</output>
19.2 hours.
The time spent studying is 19.2 /4 = 
<gadget id="calculator">19.2/4</gadget>
<output>4.8</output>
4.8 hours.
In minutes, that is 4.8 * 60 = 
<gadget id="calculator">4.8*60</gadget>
<output>288</output>
288 minutes.
