Based on the data give:
- A. The fraction of owners that prefer playing games and text messaging on their phones is 5/8.
- B. The fraction of owners that prefer taking pictures and text messaging on their phones is 3/4.
First thing you need to do is to convert all the fractions to decimals for easier calculation by simply dividing the numerator by the denominators:
Taking pictures = 3/8 = 0.375
Playing games = 1/4 = 0.25
Text messaging = 3/8 = 0.375
The fraction of owners who prefer to use their cell phones for playing games or text messaging is:
= Owners who prefer to play games + Text message
= 0.25 + 0.375
= 0.625
In fractions this is:
= 62.5 / 100
Divide both by their highest common factor of 12.5 and the simplest form is:
= 5 / 8
The fraction of owners who use their phones for pictures and text messages are:
= 0.375 + 0.375
= 0.75
In fractions this is:
= 75/ 100
Simplest form is acquired by dividing both sides by their highest common factor of 25
= 3/4
In conclusion, 5/8 of owners use their phones for both playing games and text messaging while 3/4 prefer to use it for pictures and text messaging.
