Question

okay, i totally forget how to do thisss..

Jared spends 30% of his free time watching TV. Jared has 9 hours of free time. How long does he spend watching TV?

i would like to know how to work this problem out also.

thanks so much!

Answer 1

per cent means "out of 100"

so 30% is 30/100 which is .30

so 30% of 9 hours is written as .3 x 9 = 2.7

so he spends 2.7 hours watching tv. (that is 2 hours and 42 minutes)

Answer 2

you multiply 9hours by 30%

9x30%=2.7

Answer 3

1. Jared has 9 hours of free time.

2. He spends 30% of it watching TV.

3. So what is 30% of 9 hours?

4. 30% = .30

5. 9 hours x .30 = 2.70 hours. (2 hours and .70 of a third)

6. Probably you should convert the .70 into minutes.

7. 1 hour = 60 minutes

8. 60 x .70 = 42 minutes

9. So the amount of time Jared spends watching TV is 2 hours and 42 minutes.

Answer 4

Translation:

"%" = "÷100"

"of" = "·"

30% of 9:00 = 30÷100·9:00 = 0.3·9:00 = 2:42
