cluponka [151]

Answer:

Percentage of free time Gary spends on playing video games and using internet = 54.29%

Step-by-step explanation:

Given:

Gary spends 10 hours per week on the internet.

Gary spends 9 hours per week on video games.

Gary has 5 hours free time per day.

To find the percentage of free time Gary is using to play video game and use the internet.

Solution:

Total number of hours of free time Gary has per week = 5\times 7=35

<em>[As there are 7 days in a week so we multiply by 7]</em>

Total number of hours of free time Gary spends on playing video games and using internet per week = 10+9=19

Percentage of free time Gary spends on playing video games and using internet per week can be calculated as :

⇒ \frac{\textrm{Total time spent on playing video games and using internet per week}}{\textrm{Total free time in a week}}\times 100

⇒ \frac{19}{35}\times 100

⇒ 54.29% (Answer)

Simplify fully<br> x<br> 5<br> ÷<br> x<br> 5
Ymorist [56]

Answer:

I'm going to assume this says 5x divided by 5x. Let me know if that's wrong so I can edit my answer!

Step-by-step explanation:

Since there's only 1 group of 5x in 5x, the answer is one.

If the question is x/5 divided by x/5... then, the answer is still one.

Hope this helps!
