Answer 1

decrease/original amount x 100 so 7.2/30 x100 = 24%

Answer 2

Answer : The percent decreases in the amount of time he spent watching is, 24 %

Step-by-step explanation :

As we are given that roger spent time to watching Netflix in February is, 30 hours and in march he only spent 22.8 hours watching.

Now we have to determine the percent decreases in the amount of time he spent watching.

`\text{Percent decrease in amount of time}=\frac{\text{Time spent in February}-\text{Time spent in March}}{\text{Time spent in February}}* 100`

Now put all the given values in this expression, we get:

`\text{Percent decrease in amount of time}=(30hr-22.8hr)/(30hr)* 100`

`\text{Percent decrease in amount of time}=(7.2hr)/(30hr)* 100`

`\text{Percent decrease in amount of time}=24\%`

Therefore, the percent decreases in the amount of time he spent watching is, 24 %
